WebThough less intuitive than amplitude modulation, frequency modulation is still a fairly straightforward method of wireless data transmission. We are all at least vaguely familiar with frequency modulation—it’s the origin of the term “FM radio.” If we think of frequency as something that has an instantaneous value, rather than as something that consists of … WebThe following block diagram shows a WBFM generator from NBFM signal to transmit information signal x(t) = sin(2fmt) where fm = 1 kHs. The carrier frequency of the NBFM signal is given to be fi = 100 kHz at point 1 in the block diagram and kg = 207. The required WBFM signal is required to have carrier frequency of 140 MHz and FM bandwidth BW ...
