WebJun 3, 2024 · In this case, to make the peak frequency deviation be 75kHz, I would solve for a deviation constant as follows, where Kf is my deviation constant: 75000 = Kf * abs (max (message)) 75000 = Kf * 0.9738. Kf = 77017.868 Hz/V. WebJan 31, 2011 · Answers (3) If simulink is an option, the FM Modulator Passband will do the trick. If you have the communications toolbox, you can use the FMMOD function. You could also consider this file exchange submission. This is assuming that you've already imported the WAV file into MATLAB. If not, use wavread to do this.
