How to turn sine wave into square wave?- Sine to square can be converted using a Schmitt trigger circuit.
- Schmitt trigger circuit is basically a comparator with positive feedback. Figure below shows an inverting Schmitt trigger circuit using OPAMP.
- Because of the voltage divider circuit, there is a positive feedback voltage.

**Sine wave inverters** are more efficient than square wave inverters, when it comes to the conversion of DC to AC. This ensures that the power loss is minimised, due to greater efficiency. As a consequence, your electricity bill does not shoot up. This is an immediate benefit of using a sine wave inverter.

The best Op-Amp circuit which is used to convert sine waveform into rectangular waveform is **the schmitt trigger circuit**. To avoid the false triggering, a positive feedback is used in a comparator circuit of an Op-Amp. Thus the comparator with positive feedback is called Schmitt trigger or regenerative comparator.

Sine wave inverters are **more efficient** than square wave inverters, when it comes to the conversion of DC to AC. This ensures that the power loss is minimised, due to greater efficiency. As a consequence, your electricity bill does not shoot up. This is an immediate benefit of using a sine wave inverter.

### Video answer: How to convert a modified /square wave inverter to pure sine

How does a sine wave leads to square wave?However, if a square wave is actually an infinite series of sine wave harmonics added together, it stands to reason that we should be able to prove this by adding **together several sine wave harmonics** to produce a close approximation of a square wave… A square wave is approximated by the sum of harmonics.

**pure sine wave power flows in even, arching waves, whereas modified sine wave power flows to your devices in chunky, square waves**. The square waves are giving power to your device “all or nothing,” so to speak. Your device will run properly, or not.

#### How is sine wave better than square wave?

- Pure
**Sine Wave**inverters/UPS are made to give good quality power to all electrical equipment connected to it. As you can clearly see, the**sine wave is**very close to the AC power that we get in our main grid supply.**Why Sine Wave is**Best? Sine wave inverters are much better**than square wave**inverters.

- Note: A stepped sine wave and a square sine wave are the same thing. It’s important to understand that both types of UPS system produce true sine wave output more than 99% of the time. It is only during a power failure, when the UPS is producing power from its battery reserves, the output waveform is a concern.

- Plot the square wave and overlay a sine. Normalize the x-axis by π. The generated square wave has a value of 1 for intervals [nπ,(n+1)π) with even n and a value of -1 for intervals [nπ,(n+1)π) with odd n. The wave never has a value of 0. plot(t/pi,x,'.-',t/pi,sin(t)) xlabel('t / pi') grid on.

Can a square wave be converted to a sine wave?- You can certainly use active filters (filters incorporating an op-amp)
**to**convert**a**square**wave to a**sine wave. They have the advantage of maintaining the amplitude of the signal but are fairly complicated and require a number of additional components. They are also limited**to a**fixed frequency response.

**To**know**how**the**square wave to**sine**wave**converter works, one needs to understand what is happening**in**each RC filter stage.**In**the first RC network stage, it has**a**resistor**in**series and capacitor**in**parallel. The output is available across the capacitor. The capacitor gets charged up via the resistor in series.

- With an LC resonant at the output of the 555 timer, the square
**wave**signal is converted into**a sine wave**signal,**a**signal that is very much**sine wave**like. But**in**order for this**to**happen, the right values must be chosen for the LC resonant circuit, or else it will not work.

**A square wave**to**sine wave**converter**can be**built using 6 passive components, namely capacitors and three resistors. Using these three capacitors and three resistors,**a**3 stage RC network can be built that takes**a square wave as**an input and**sine wave as**an output. A simple single stage RC network circuit is shown below.

To convert a sine wave into square wave using Simulink, you can **use the 'Sign' block within 'Math Operations' Library**. The model describing the equation can be viewed in the attachment.

#### Why are sine waves so used and important?

- Why are Sine Waves So Used and Important? Sine waves are so important and so studied because the sine wave is the most basic and the
**most common waveform for AC Signal variations**. A rotary generator is a very important device that allows us to have electricity in our homes.

- Modified
**Square Wave**: This waveform is a compromise between the**sine wave**and the square wave. The positive and negative pulses of the**square wave**are thinned, separated and made taller, so the peak voltage is much closer**to**that of a**sine wave**, and the overall shape of the**wave**more closely resembles that of a sine wave.
