Q. Zero crossing detectors is also called as
Solution:
- In zero crossing detectors, the output waveform is always a square wave for the applied sinusoidal input signal.
- Basically it is a voltage comparator whose output changes when the input signal crosses the zero of the reference voltage level.
- It find applications in electronics circuits mainly for switching purpose and in phase locked loop. Also, they are used in frequency counters and in phase meters.
