Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing. In analog frequency modulation, such as radio broadcasting, of an audio … See more
If the information to be transmitted (i.e., the baseband signal) is and the sinusoidal carrier is , where fc is the carrier's base frequency, and Ac is the carrier's amplitude, the modulator combines the carrier with the … See more
FM provides improved signal-to-noise ratio (SNR), as compared for example with AM. Compared with an optimum AM scheme, FM typically has … See more

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 … See more• Analog Modulation online interactive demonstration using Python in Google Colab Platform, by C Foh. See more
