Consider the circuit shown in Figure (i). If the diode used here has the V-I characteristic as in Figure (ii), then the output waveform V0 is—
Correct Option: C
From given figure given that resistance of diode Rf = | = 300 Ω | dI |
and the diode will conduct for input voltage greater than 0.5 V.

The complete equivalent circuit of the diode can be given as for the positive half cycle.

so, V0 = (Vi – 0.5). | (600 + 300) |
or V0 = 1.5 × | 900 |
or V0 = 1.0 V
However, for the negative half cycle of the input voltage Vi, the diode is in the non-conduction stage and we get zero output.
Hence alternative (C) is the correct answer.
