Q3) (c)

Explain the difference between clipping and clamping circuit. A positive voltage clamping circuit and a positive voltage clipping circuit each have ±12 V square Wave input. Sketch the output waveform for each circuit.

Key Differences Between Clipper and Clamper

  • Clipper limits the voltage while clamper shifts upwards or downwards.
  • Clipper does not require capacitor while clamper circuit cannot be completed without energy storing element, i.e. capacitor.
  • The output waveform obtained from clipper circuit appears in a different shape than that of input, while the shape of the waveform in the clamper circuit remains exactly same after clamping of the signal.
  • The clipper is also known as a current delimiter, voltage delimiter, or amplitude delimiter while clamper circuit is also considered as a voltage multiplier circuit.
