1 Answer

Answer :

image

i) Input signal: - The information can be in the form of sound, picture or data coming from computer.

ii) Input transducer: - it converts original information into equivalent electrical signal.

iii) Transmitter: - it converts electric equivalent into suitable form. It increases the power level of signal so that it can cover long distance.
