B)Square law
C)Inverse relationship
D)Superheterodyne

Question

Quizplus · Accepted Answer

The synchronous detector relies on the principle of phase-locked loop, which helps in detecting and extracting the information signal from the modulated carrier wave. The phase-locked loop is a closed-loop feedback system that aligns the phase of the local oscillator with the phase of the incoming carrier. This alignment leads to the coherent addition of the modulated signal and the local oscillator, leading to the detection of the information signal. Square law and inverse relationship are not directly related to synchronous detection, and the superheterodyne is another type of receiver architecture.
