What does a clipper circuit do to a waveform?

  • A.Multiplies the peak amplitude by a fixed factor
  • B.Converts the waveform to a train of narrow pulses
  • C.Removes the part beyond a chosen level
  • D.Shifts the whole waveform to a new direct level

Answer: C

A clipper cuts off whatever lies beyond a reference level, leaving the rest untouched, which is how a waveform is limited or a peak protected. Shifting the direct level is a clamper's job, multiplying the peak is a voltage multiplier's, and pulse generation is something else again. Clipping and clamping are constantly confused because both use a diode and a reference, so it is worth fixing which one alters the shape and which one alters the position.
