  1. A clipper circuit is shown below.

    Assuming forward voltage drops of the diodes to be 0.7 V, the input-output transfer characteristics of the circuit is




Correct Option: C

When – 0.7 V < V1 < 5.7 V output will follow input, because zener diode and normal diodes are off
When Vi ≤ – 0.7V, Zener diode forward bias and V0 = – 0.7 V
When Vi ≥ 5.7V, diode is for war d bias and V0 = 5.7V
