Detailed explanation-1: -In frequency-division multiple access (FDMA), the available channel bandwidth is divided into many nonoverlapping frequency bands, where each band is dynamically assigned to a specific user to transmit data.
Detailed explanation-2: -Explanation: The bandwidth of FDMA channels is relatively narrow as each channel supports only one circuit per carrier. That is, FDMA is usually implemented in narrow band systems.
Detailed explanation-3: -Every signal is associated with a range of frequencies called the frequency band. The difference in the highest and lowest frequencies in the band is known as the bandwidth of the signal. It is a characteristic of the signal and signifies the detailing of the information in the signal.
