Hi everyone. Basically, i am generating a ".wav" file using the code below in MATLAB Fs = 14400; duration = 20; t = linspace(0 , duration , duration*Fs ); m = cos(2*pi*10*t); A = 1.5; f_c = 200; s = (A + m).*cos(2*pi*f_c*t); plot(s) s = s / max(s); % sound(s, Fs); audiowrite("deneme.wav", s, Fs);…

How can i get a similar AM waveform?

If you plot points instead of lines you may notice that analogRead() happens to take at most 4 samples from a full wave.

Get a faster ADC or lower carrier frequency.
