1.	The transmitter-receiver combination in the satellite is known as a _______(a) Relay(b) Repeater(c) Transponder(d) DuplexerI have been asked this question during an online interview.This intriguing question originated from Satellite Communication Systems in chapter Satellite Communication of Avionics
Answer» Right answer is (c) Transponder Explanation: The transmitter-receiver COMBINATION in the satellite is known as a transponder. The BASIC FUNCTIONS of a transponder are amplification and frequency TRANSLATION. The reason for frequency translation is that the transponder cannot transmit and RECEIVE on the same frequency.
