Synchronous detection of AM signal - Requirements & Disadvantages
Q. Requirements of synchronous detection of AM signal are:- Published on 13 Oct 15a. Local generation of carrier
b. The frequency of the locally generated carrier must be identical to that of transmitted carrier
c. The phase of the locally generated carrier must be synchronized to that of transmitted carrier
d. All of the above
ANSWER: All of the above
Synchronous detection of AM signal requires local generation of the carrier signal at the receiver. The frequency of the locally generated carrier must be identical to that of transmitted carrier. And the phase of the locally generated carrier must be synchronized to that of transmitted carrier otherwise the detected signal would get distorted.
