“A communication satellite is essentially a repeater station in space.” Justify this statement by analysing the function of a repeater.
The functions of a communication satellite are as given below:
(i) Picks up the signal transmitted by transmitter.
(ii) Amplifies it.
(iii) Retransmits it towards information users.
These all are also functions of repeater to receive, amplify and retransmit the signal.
