Those interested in the Analog waves category often ask the following questions:

### ☑️ Why sqare waves are called analog waves?

A square wave is a sum of an infinite number of sine waves (analogue). These sine waves consist of one wave called a FUNDAMENTAL, and all of the other waves are called HARMONICS. The fundamental is the same amplitude and frequency as the square wave. The harmonics are all odd, i.e. mathematically, the first harmonic (which is called the 3rd harmonic) is 1/3 the amplitude and 3 times the frequency of the fundamental. The next harmonic (called the 5th harmonic) is 1/5 the amplitude and 5 times the frequency of the fundamental. And so it goes with the next harmonic (the 7th), followed by the 9th and so on ad infinitum.

### ☑️ What are analog signal waves?

Analogue signals are transmitted using a continuously changing quantity as a reference. Data transmission consists of sending signals as continuous waves. An example of an analogue signal is the transmission of radio waves, television waves or sound waves.

### ☑️ What is the difference between analog and digital waves?

• Analog signal is a continuous wave that keeps on changing over a time period. Digital signal is discrete in nature. The fundamental difference between analog and digital signal is that analog signal is represented by the sine waves whereas, the digital signal is represented by square waves.

### ☑️ How are analog sound waves converted to digital sound?

• Digital audio. An analog audio system converts physical waveforms of sound into electrical representations of those waveforms by use of a transducer, such as a microphone. The sounds are then stored on an analog medium such as magnetic tape, or transmitted through an analog medium such as a telephone line or radio.

### ☑️ What is analog sound and example of analog sound?

analog audioRefers to recording audio in a format of continuous vibrations that are analogous to the original sound waves. Before audio recording became digital, sounds were "carved" into vinyl records or written to tape as magnetic waveforms. Contrast with digital audio

### Can an analog signal be a square wave?

Sine waves and square waves are two common analog signals. Note that this square wave is not a digital signal because its minimum value is negative.

### A pure sine wave is analog or digital?

Sine waves and square waves are two common analog signals. Note that this square wave is not a digital signal because its minimum value is negative.

### How to make a sine wave analog electonics?

• A popular way to make a sine wave oscillator is to use an RC network to produce a 180 degree phase shift to use in the feedback path of an inverting amplifier. Setting the gain of the amplifier to offset the RC network attenuation will produce oscillation.

### How does an analog lp record sound like?

• Analog - LP Records. The old LP record format is totally analog. The sound signal is recorded as little hills and valleys in the plastic groove that runs around the record. For playback, a needle sits in the groove, the record spins, and the hills and valleys make tiny up and down movements of the needle.

### Why sine wave is represent in analog signal?

An analog signal is simply a quantity varying continuously over time..But because we are interested in information and communication, we are usually interested in rapidly varying signals that have some underlying periodicity. Therefore we use sin wave

### Is a square wave an analog or digital wave?

This question has become the point of much heated debate here on WikiAnswers, and I will attempt to pare down the answers to its simplest form while keeping all valid viewpoints intact. Any further debate should be put in the "Discussion" area.The Case For Digital: With a few exceptions, a square wave in it's theoretical form will most likely be used in digital applications.A square wave may be "analog" during the time it is in transition from one stable state to another, and "digital" when it is in one state or the opposite state (i.e., voltage level), according to the type of digital inputs stimulated, but a transition is not an analog state function in the context of computers or digital logic. A square wave has two states hi and low and the transition from hi to low can be switched up to gigahertz (GHz) frequencies. Test equipment manufacturers are able to generate square wave signals well above 100GHz. Function generators have the square wave signal where the transition can be controlled. Practically all digital circuits utilize these states as "1" and "0" (or true and false) that computers use to make decision at the machine language level. Furthermore all modern computer uses this signalling scheme. But digital signals (1's and 0's) are not necessarily "square" waves, strictly speaking. A clock circuit generates a square wave that is used as a timing reference for the address, data, and control circuits.The Case For Analog: All theoretical waveforms look great on paper, but it is impossible to produce any perfect waveform. Therefore, all waveforms (including square waves) are inherently analog.By Fourier Analysis, a square wave is actually an infinite series of the summation of sine waves, in this case the odd harmonics divided by N. As a result, a square wave can actually be considered an analog signal. Looking at this another way, no pulse driver, conductor, or transmission line is perfect, so the rise and fall time of a square wave are not instantaneous, meaning that the series is not really infinite so, again, the square wave is analog, although quite complicated, but still analog. We call it digital because we sense it with discriminators that decide the "value" of the wave based on some thresholds with appropriate hysteresis.The Case For Sanity: A wave form is not inherently digital or analog. "Digital" and "analog" are arbitrary words used to describe an application of waveforms. In other words, all digital signals are square waves, but not all square waves are digital.A square wave is usually used in digital applications, but is also used in audio applications for a "distorted" guitar or vocal effect. A sine wave can become a square wave if the input signal on an amplifier is too great for the power of the circuit to amplify, "clipping" the high and low portions of the sine wave.A square wave can be considered an analog or a digital signal. A perfect square wave (not possible to generate based on Fourier Analysis) would not in general be considered an analog signal because it only has two values, defeating the point of analog (in many cases, but not all). One can make a square wave oscillator to use as an alarm - different frequencies were used to convey different information. A square wave was simple to create, thus my reason for using as opposed to a sine wave (this is an example of an analog use of square waves - the information is not stored in the two values of the wave, but in the "infinite frequency range made available by the extra circuitry to change frequencies."This point is moot, really, because it is the nature of the data (being analog or digital) that truly is important, and defines whether the wave should be catagorized as "analog" or "digital".Oh-So-Clever Analogy: A wrench is the perfect tool for fixing trucks, but if I use the wrench to fix a desk, that doesn't make the desk a truck. In short, the application defines the state, but does not limit the tool.

### Which is the analog of the monochromatic electromagnetic wave?

### What does digital recording do to an analog sound wave?

It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.

of course

### What are three key parameters of an analog sine wave?

Frequency, amplitude, and phase.

### Are sound waves transverse waves or longitudinal waves?

Generally, sound is classically defined as longitudinal waves in a medium.However, sound can also behave as a transverse wave in solids

### Are surface waves compression waves or transverse waves?

First, it's not called compression wave but a longitudinal wave, second, neither and both because it's a mix of both. For it looks like a transvers, but moves in circles like a longitudinal wave.

### Are sound waves longitudinal waves?

Yes. Sound waves are longitudinal waves.

### Are radio waves mechanical waves?

Water waves and sound waves are examples of mechanical waves… Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays.

### Which waves are longitudinal waves?

• sound waves.
• ultrasound waves.
• seismic P-waves.

### Which waves are compressional waves?

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'.

### Are light waves compression waves?

• compression occur when the particles are closer than normal to each other while rarefaction occur when particles are farther than normal to each other. Ocean and light waves are transverse waves and do not contains compressions and rarefactions.

### Is s waves transverse waves?

'S' is a common designator which refers to a transverse body wave.

### Are sound waves really waves?

Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner. Do not be misled - sound waves traveling through air are longitudinal waves.

### Are seismic waves compression waves?

There are four types of seismic waves, the P-wave, S-wave and the Love and Rayleigh waves. Of these four types, the P-wave is a longitudinal / compression wave.

### Are light waves electromagnetic waves?

Usually when one says light waves, one is referring to Visible light. Any light wave, and hence visible light, is an electromagnetic wave. As an electromagnetic wave, it is also a transverse wave. The oscillating electric and magnetic fields of an electromagnetic wave in free space are oscillating with a direction perpendicular yo the direction of movement of the wave. The velocity of an electromagnetic wave is the sped of light. This is a sensible things since light is an electromagnetic wave. In a vacuum all electromagnetic waves travel at the same speed. In matter, if the matter allows an electromagnetic wave to propagate, the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction, v=c/n. Electromagnetic waves, like all waves, have velocity, wavelength, frequency, amplitude and phase. As with all transverse waves, electromagnetic waves can be polarized, or we say, have a polarization. Electromagnetic waves have electric and magnetic fields that are sinusoidal in space and time. These electromagnetic fields satisfy Maxwell's equations, i.e. the fundamental laws of electromagnetism. There is a quantum version of electromagnetic theory called electrodynamics and that theory is the necessary edification of Maxwell's equations to describe the quantum nature of light. Thus, even when we are discussing light as photons, it is correct to say light is an electromagnetic wave as such is manifested within quantum electrodynamics.

### Are pressure waves longitudinal waves?

Longitudinal waves travel in a medium due to alternate compression & rarefactions ie. they travel due to variation in pressure.

### Are light waves longitudinal waves?

No, light waves are not longitudinal waves. Light is an example of a transverse wave, like a wave moving across the surface of water. Sound or seismic waves are examples of longitudinal waves.

### Are sound waves circular waves?

• When the airplane is flying below Mach 1, the sound waves it generates form a circular shape as a whole. However, when the airplane exceeds Mach 1, then the sound waves it generates form a conical shape as a whole. This is explained by the "falling behind" phenomena, mentioned above in the second paragraph.

### Are surface waves compression waves?

No. surface waves on the surface of water is transverse in nature. It has crests and troughs. Compression and rarefaction will be in longitudinal wave. example sound waves.

### What waves are electromagnetic waves?

your question is kind of general, but i would say a transverse wave.

### Are water waves longitudinal waves?

• Water waves are surface waves, a mixture of longitudinal and transverse waves. Surface waves in oceanography are deformations of the sea surface. The deformations propagate with the wave speed, while the water molecules remain at the same positions on average. Energy, however, moves towards the shore.

### Are infrared waves sound waves?

No; sound is a mechanical wave, infrared is a part of the electromagnetic spectrum.

### Are lamb waves ultrasonic waves?

"Ultrasonic" is an adjective referring to sound waves at frequencies greater than the typical limit of human hearing. "Lamb waves" are elastic waves propagating in solid plates. Their particle motion lies in the plane that contains the direction of wave propagation and the plate normal (the direction perpendicular to the plate). The characteristic that defines a "Lamb wave" is completely different from the characteristic that defines an "ultrasonic" wave, so the question is a lot like asking "Are human beings American people ?" Some Lamb waves are ultrasonic, and the rest aren't.

### Are radio waves sound waves?

Radio waves can carry sound signals. But by definition radio waves are not sound waves. Radio waves can travel in a vacuum, but sound waves need a physical medium.To explain the apparent contradiction, the sound wave is converted to an electrical signal version that is then used to modulate the radio signal.No it is not

### Are electromagnetic waves mechanical waves?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

### Are electromagnetic waves transverse waves?

Electromagnetic waves have a transverse component.

### Are sound waves mechanical waves?

Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.

### Are sound waves pulse waves?

Sounds waves can be either pulse waves or periodic waves. A pulse wave is characterized as one assault to the medium while periodic waves are characterized as a series of successive assaults on the medium. Sound waves can be described by period, wavelength, amplitude, and for periodic waves we can include frequency.

### Are radio waves and light waves both electromagnetic waves?

• Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms.

### Which waves are faster p-waves or s-waves?

P waves (Primary waves) are faster than S waves (Secondary waves). In case you were wondering, these two waves are body waves.

### What are p waves s waves and l waves?

P waves travel fastest and are the first to arrive from the earthquake… The different S waves arrive after the P waves. The slowest (and latest to arrive on seismograms) are surface waves, such as the L wave. L waves are named for the Cambridge mathematician A.E.H. Love who first described them.

### Surface waves refracted s waves secondary waves primary waves have the highest velocities?

Primary waves (or P-waves) have the highest velocities because they move as a compression wave (like sound waves) rather than shear waves (like ocean waves).

### Which waves have lower frequency radar waves or visible waves?

Visible waves have the higher frequency. Radar waves are lower

### Are p-waves and s-waves transverse or longitudinal waves?

P-waves are longitudinal and S-waves are transverse waves.

### Is there any difference between an analog signal and a wave signal?

A Digital Signal can have one of two values, 1 or 0. An Analogue signal can have any value between 1 and 0. Digital signals are better for sending information as if the signal is somewhat distorted, it is still easily recognisable. Vinyl Record use analogue. Cds use Digital

### Where can one find the best digital audio to analog audio converter?

Aaptiv, the number one audio fitness app, streams audio-based fitness classes that combine the guidance of a trainer with the perfect playlist, giving you a better way to workout. cutt.us/JjQzS

### Compare mechanical waves and elctromagnetic waves?

An electromagnetic wave is capable of passing through a vacuum (space). All light waves are electromagnetic waves. Mechanical waves are not able to pass through space. They require a medium to pass their energy from one place to another. An example of a mechanical wave is a sound wave.

### Which waves are called heat waves?

The wavelength of infrared waves are sufficient to set atoms and molecules into vibrational motion. Hence whenever an object is encountered with infrared waves, produces heat due to the vibrations of atoms. This is the reason why infrared waves are called heat waves.

### Are transverse waves the travelling waves?

• If the displacement of the individual atoms or molecules is perpendicular to the direction the wave is traveling , the wave is called a transverse wave. If the displacement is parallel to the direction of travel the wave is called a longitudinal wave or a compression wave.
