1.	What device is used to prevent power from the transmitter from going to the receiver side?(a) Multiplexer(b) Duplexer(c) Monoplexer(d) FilterThis question was addressed to me in semester exam.This is a very interesting question from Radio Transmitters in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» Correct OPTION is (b) Duplexer The explanation is: A duplexer is a device that is PLACED just before the antenna in a TRANSDUCER SYSTEM. It is BASICALLY a switch which allows both transmission and reception but only one at a time.
