GATE Electronics and Communication Engineering Practice Quiz

Question 1

An ideal diode is connected in series with a resistor to form a positive clipper. The input is a sinusoid of peak value 10 V, and the diode is oriented so that positive half cycles appear at the output while negative half cycles are blocked. What is the minimum output voltage over one full cycle?

Accepted Answer

0 V

Question 2

In a clipper circuit, a sinusoidal input v_i = 8 sin(ωt) V is applied to an ideal two-sided limiter with clipping levels at +6 V and -2 V. Which statement about the output is correct?

Accepted Answer

Both positive and negative peaks are clipped, but by different amounts

Question 3

An ideal series clipper is designed to remove all portions of the input below +2 V by using a DC bias source. For an input ramp from 0 V to 5 V, what is the output when the input is 1 V?

Accepted Answer

0 V

Question 4

A symmetrical clipper uses two ideal diodes and DC references to limit the output to ±5 V. If the input is a triangular wave varying from -8 V to +8 V, what is the output peak-to-peak value?

Accepted Answer

10 V
