This MATLAB function returns a demodulated signal z, given the input frequency modulated (FM) signal y, where the carrier signal has frequency Fc and sampling rate Fs.
Classic FM Demodulation, using MatlabStarted by all4dsp ●January 22, 2015Chronological Newest First I've got a real voltage versus time waveform (e.g. xr) of a carrier frequency that is FM modulated. I need to see the modulation waveform to determine its peak-to-peak amplitude. While I...

번역 편집:Joseph Swelland2018년 6월 3일 EDIT: I've seen a previous answer from 2009, but I'm not sure if the documentation has changed in the last decade and I'm not sure how to check. I am trying to design a phase locked loop for FM demodulation in MATLAB and am ...
Ais the carrier amplitude. fcis the carrier frequency. x(τ) is the baseband input signal. fΔis the frequency deviation in Hz. The frequency deviation is the maximum shift fromfcin one direction, assuming|x(τ)| ≤ 1. A baseband FM signal can be derived from the passband representation ...
