Bandwidth

The term in question is obviously composed of “band” and “width.” This “band” refers to a band or range of frequencies, and “width” refers to the appearance of this band when viewed in the frequency domain. The bandwidth of a signal is defined as the difference between the upper and lower frequencies of a signal generated. It is measured in terms of Hertz(Hz) i.e. the unit of frequency.

Let’s understand this better with the help of an example. Whenever you tune into a radio you find various stations at varying particular frequencies. The bandwidth of FM radio is 200 KHz from 88.1 MHz to 101.1 MHz for most places.
