WebFrequency modulation (FM) In frequency modulation, the frequency rather than the amplitude of the carrier wave is made to vary in proportion to the varying amplitude of the modulating signal, as shown in Fig. 9.19 d. A simple method to achieve FM is to vary the capacitance of a resonant LC circuit in a transmitter. WebThis Recommendation provides the necessary bandwidth formulae.
