WebTo make your life easier, I suggest you stop using the cosd () command and only use MATLAB's cos () command. For your AM code, if variable dt1 is measured in seconds then your Fs sampling rate is 10,000 samples per second. But your carrier frequency fc1 is set to 500,000. If your fc1 = 500,000 is measured in Hz (cycles/second) then your fc1 ... WebNov 12, 2024 · MATLAB Code: Output: Frequency Modulation in MATLAB. For different modulation index (B): Output: For FM, one can even use the in-built function for the Frequency modulation i.e. fmmod...

WebAug 18, 2014 · It's a built in MATLAB function, read about it in the MATLAB documentation for further info. (doc awgn) Theme clear Fs = 800; % Sampling rate of signal Fc = 30; % Carrier frequency t = [0:Fs-1]'/Fs; % Sampling times x = sin (2*pi*2*t); % Channel 1 dev = 20; % Frequency deviation in modulated signal y = fmmod (x,Fc,Fs,dev); % Modulate … 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. brakes for less.com
