Facts A clipper is an electronic circuit that produces an output by removing a part of the input above or below a reference value. That means the output of a clipper will be the same as that of the input other than the clipped part. Due to this, the peak to peak amplitude of the output of a clipper will be always less than that of the input. The main advantage of clippers is that they eliminate the unwanted noise present in the amplitude of an ac signal. Question: What do you think is the main disadvantage of a Clipper circuit over a Clamper Circuit?
