Detailed explanation-1: -Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum.
Detailed explanation-2: -The spectrum of a signal is the range of frequencies contained in the signal. The bandwidth is the difference between the lowest and highest frequency in the spectrum. It is therefore the width of the spectrum and is a measure of the information carrying capacity of the signal.
Detailed explanation-3: -Bandwidth is the quantity of data that a connection can send per unit of time. On the other hand, the frequency is the number of data packets received per unit of time. The frequency of a signal is given in cycles per second. In contrast, the bandwidth is often specified in bits per second.
Detailed explanation-4: -The bandwidth of a composite signal is the difference between the highest and the lowest frequencies contained in that signal.
