If diodes are ideal in the circuit shown in the given figure, then determine the maximum value of Vout during the positive half of the input signal.

If diodes are ideal in the circuit shown in the given figure, then determine the maximum value of Vout during the positive half of the input signal. Correct Answer 4V

To find out the output waveform let us do the analyse of the circuit at various input voltage level.

1) Vin < -6 V; D1 = off, D2 = on; V0 = -6V

2) -6V < Vin < 4; D1 = off, D2= off; V0 = Vin

3) Vin > 4 V; D1 = on, D2 = off; V0 = 4V

Output waveform can be plotted as:

∴ Maximum value of Vout during the positive half of input signal is 4 V.
