FSK synchronous detection is _________ more sensitive than asynchronous heterodyne detection.

FSK synchronous detection is _________ more sensitive than asynchronous heterodyne detection. Correct Answer 0.45 dB

During FSK detection, the probability of error is increased with respect to direct detection as a result of amplified noise from the orthogonal polarization. Thus, the synchronous detection is more sensitive than the asynchronous heterodyne detection.
