In electronics, a clipper is a circuit designed to prevent a signal from exceeding a predetermined reference voltage level. A clipper does not distort the remaining part of the applied waveform. Clipping circuits are used to select, for purposes of transmission, that part of a signal waveform which lies above or below the predetermined reference voltage level.   A biased clipper comes in handy when a small portion of positive or negative half cycles of the signal voltage is to be removed. ... Thus a biased negative clipper removes input voltage when the input signal voltage becomes greater than the battery voltage. QUESTION: Where do we exactly need to use a clipper circuit? State at least 3 examples and why it's needed on that application or device.
