Answer is:
Recovering the low frequency modulating signal from the received signal
Explanation:
Demodulation?is extracting the original information-bearing signal from a modulated carrier wave. A?demodulator?is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave.
Answer is:
extending communication range
Explanation:
In telecommunications, a?repeater?is an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances.
