Analog Communication - Electronic Engineering (MCQ) questions & answers for Q. 13707
Q. In Automatic gain control of the AM receiver- Published on 14 Oct 15a. Gain of the receiver is adjusted
b. The gain adjustment depends upon the strength of the received signal
c. The output provided is a DC voltage
d. All of the above
ANSWER: All of the above
The automatic gain control (AGC) circuit is used to adjust the gain of the receiver depending upon the strength of the received signal at the receiver. The AGC gives a DC voltage as an output that is proportional to the amplitude of the received signal. In AGC, the output is a linear function of the input.
