Question

An AM signal is detected using an envelope detector, the carrier frequency and modulating signal frequency are 1 MHz and 2 kHz respectively. An appropriate value for the time constant of the envelope detector is-A-500 &mu; secB-20 &mu; secC-0.2 &mu; secD-1 &mu; sec-B-20 &mu; sec

APTITUDE CRACK · Accepted Answer

B 20 &mu; sec  In envelope detector, for proper detection 10 6 ≤ RC ≤ 250 μ sec. Only 20 m sec satisfies the condition.
