Question

In the given circuit, given that C=2MF and diode cut-in voltage, Vγ =0. Calculate the average output voltage.

(a) 2V

(b) 4V

(c) -2V

(d) -3V

I have been asked this question in unit test.

Asked question is from Clamper Circuit in division Diode Circuit of Analog Circuits

Answer 1

Right option is (c) -2V

The best I can explain: Maximum input is Vm = 32 + 5 = 37 V

Capacitor charges up to  37 – 3 = 34 V

Vout = Vin – Vc = 32 + 5 sinωt – 34 = -2 + 5sinωt

Average output voltage = – 2 V.
