1.	Identify the device which is a combination of a transmitter, an amplifier and a receiver which picks up a signal and retransmits it.(a) Multi-tandem transmitter(b) Repeater(c) Amplifier(d) ModemThis question was addressed to me in a job interview.The doubt is from Basic Terminology Used in Electronic Communication Systems in portion Communication Systems of Physics – Class 12
Answer» RIGHT CHOICE is (b) Repeater Best EXPLANATION: A repeater is a combination of a transmitter, an AMPLIFIER and a receiver which picks up a signal from the transmitter, amplifies and retransmits it to the receiver sometimes with a change of carrier frequency.
