उत्तर
The function of a transducer is to convert one form of energy into another form. A microphone at the transmitting station is one of the examples of a transducer.
The function of a repeater is to regenerate the signal which can be transmitted forward. A repeater is a combination of a receiver, amplifier, and a transmitter. A repeater receives the signal, amplifies it and then retransmits it forward.
