1.	Squelch circuit is normally inserted in receiver ________(a) after detector(b) before detector(c) before mixer(d) after power amplifierI got this question during an interview.I'm obligated to ask this question of Linear Modulation topic in portion Amplitude Modulation of Analog Communications
Answer» Correct answer is (a) after detector For explanation I would say: Squelch is a circuit that acts to SUPPRESS the audio (or video) OUTPUT of a receiver in the absence of a SUFFICIENTLY strong desired INPUT signal. Squelch is added to suppress NOISE. It is added after detector when there is no carrier.
