WebPhase modulation (PM) is a simple contrasted to Frequency modulation (FM). It is used to find out the velocity of a target by removing Doppler data. This needs constant carrier which is achievable during phase … WebIt turns out that phase modulation is more relevant in the context of digital RF. In a way, though, we can say that PM radio is as common as FM radio simply because there is little difference between phase modulation and frequency modulation. FM and PM are best …
