under which category will it come?i think that this question is paramount bcos all our receivers were fitted with Envelope detector(...indeed a well known fact)

Hi electronics_kumar,

I'm not sure about this, I think the envelope detector is present there in the synchronous detector as well as the asynchronous detector. Its present in all our detectors because all our detectors ,at least 90% of them, are super heterodyne recievers which need a detector (most popular being the envelope detector as its the most compact and the one with the least cost and parts).

sychronising has to do with phase(in some cases frequency)....


as an envelope detector just takes out the amplitude . there is no Question of synchronisation here..
