WebSep 26, 2024 · What are different methods of FM generation? FM signals can be generated using either direct or indirect frequency modulation: Direct FM modulation can be achieved by directly feeding the message into the input of a voltage-controlled oscillator. For indirect FM modulation, the message signal is integrated to generate a phase-modulated signal.
