What will be the frequency of output waveform of square wave generator?

What will be the frequency of output waveform of a square wave generator if R2 = 1.16 R1? Explanation: When R2= 1.16 R1, then fo = 1/2RC× ln[ (2R1+ R2) / R2] = 1/2RC ×ln [(2R1 + 1.161R1 )/ (1.161R1)] = 1/( 2RC×ln2. => Frequency= 5khz , f =1/t = 0.2ms.

What is the output of square wave generator?

From the above figure we can observe that the output of square wave generator will have one of the two values: +Vsat and −Vsat. So, the output remains at one value for some duration and then transitions to another value and remains there for some duration.

What is the time constant in Schmitt trigger square wave generator?

Like the previous Schmitt waveform generators circuit above, the frequency of oscillation is determined by the R1C time constant which is given as: 1/2.2R1C.

Why inductors are not preferred for audio frequency?

Why inductors are not preferred for audio frequency? Explanation: At audio frequencies, inductor becomes problematic, as the inductors become large, heavy and expensive. This is because of the variety of cheaper op-amp and the absence of inductor’s.

How is a zero crossing detector a square wave generator?

In this way, the zero crossing detector detects the change in the level of the applied signal. From the beginning, we are mentioning that a zero crossing detector is also known to be a square wave generator. As the output of the window comparator is nothing but a square wave.

When does a zero crossing detector shift to positive?

It shifts negative to positive when sine wave crosses positive to negative and vice versa. This is how a Zero Crossing Detector detects when the waveform is crossing zero every time. As you can observe that the output waveform is a square wave, so a Zero Crossing Detector is also called a Square wave Generator Circuit.

How is a zero crossing sine wave passed through a circuit?

For an input sine wave, the output of the zero-crossing detector being a square wave, is further passed through an RC series circuit. This is shown in the figure below.

Can a comparator be used as a zero crossing detector?

The zero-crossing detector circuit is a main application of the comparator circuit. It can also be named as the sine to square wave converter. For this, any one of the inverting/ noninverting comparators can be used as a zero crossing detector.
