Modulate and Demodulate FM Signals in Simulink
Modulate and demodulate a sinusoidal signal using FM Modulator Baseband and FM Demodulator Baseband blocks.
The fmmoddemod
model generates a sine wave of frequency 4 Hz and amplitude 1 V. The FM Modulator Baseband block sets the frequency deviation to 50 Hz.
The Modulated Signal scope shows that the frequency of the modulator output, Mod Sig
, varies with the amplitude of the input data.
The Demodulated Signal scope demonstrates that the output of the demodulator, Demod Sig
, is perfectly aligned with the input data.
