Question

Give the bandwidth of telephone communication system.

Answer 1

Bandwidth is a broad term defined as the bit-rate measure of the transmission capacity over a network communication system. Bandwidth is also described as the carrying capacity of a channel or the data transfer speed of that channel. ... Bandwidth exists in physical or wireless communication networks.

For example, the bandwidth allocation of a telephone voice grade channel, which is classified as narrowband , is normally about 4,000 Hz, but the voice channel actually uses frequencies from 300 to 3,400 Hz, yielding a bandwidth that is 3,100 Hz wide.
