FAQ

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

☑️ 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.

☑️ 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.

☑️ Is a square wave 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 does an analog wave look like?

An analog wave is similar in shape to whatever it represents. The idea is that (for example) when you speak, you can represent the pressure difference by a certain curve. When this is converted (in a microphone) to an electrical current, the graph of the electrical current will be similar (i.e., analog) to the graph for the sound wave.

What makes a sound wave an analog signal?

  • A sound wave is an analog signal. Sound waves are created by vibrations, and sound can be recorded on vinyl records with grooves that cause the needle on a record player to vibrate. Those vibrations are then amplified to play back the sound that was originally recorded. The pitch, or frequency, of that sound can take on a wide range of values.

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.

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 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.
