Bandwidth?is also defined as the amount of data that can be transmitted in a fixed amount of time. For digital devices, the?bandwidth?is usually expressed in bits per second(bps) or bytes per second. For analog devices, the?bandwidth?is expressed in cycles per second, or Hertz (Hz).

Answer is:
superimposing low frequency message on a high frequency wave carrier
Explanation:
In electronics and telecommunications,?modulation?is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a?modulatingsignal that typically contains information to be transmitted.
Answer is:
AM/FM
Explanation:
Modulation used in radio is generally AM/FM
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.
