Fm generation methods
WebThe FM signal with high f cfc and high m fmf is then passed through a class C power amplifier to raise the power level of the FM signal. The Armstrong method uses the phase modulation to generate frequency modulation. This method can be understood by dividing it into four parts as follows: 1 Generation of FM from phase modulator: WebLECT-22: GENERATION OF FM WAVE (DIRECT & INDIRECT METHOD)
