Ofcourse BW will play its own role. But, present situation limitation of ADC speed, signal processing chip speed limitation and high data rate modem implementation complexity will play the major...
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.
Absolute bandwidth is the relative bandwidth of the signal (B) times the center frequency (f0). For example , by increasing the center frequency, the relative bandwidth is unchanged, but the absolute...
