1.	What circuit provides the initial selectivity in a receiver?(a) Amplifier(b) Attenuator(c) Multiplexer(d) LC tuned circuitsI had been asked this question in an online quiz.My question is from Communication Receivers topic in portion Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» CORRECT choice is (d) LC tuned circuits To explain: Initial selectivity in a receiver is normally obtained by using LC tuned circuits. By CAREFULLY controlling the Q of the resonant circuit, we can set the DESIRED selectivity.
