MATLAB simulation of modulation/demodulation onto a Discrete-Time Carrier
Working on a lab and have hit a spot where I do not know how to proceed modulating the sampled waveform onto a discrete-time sinusoidal carrier and then performing the next step with the three channels (part 4.1 subsection 3 and 4 of link). Please any help would be appreciated. This is what I have so far for the first two subsections of 4.1.lab steps in image
%read audiofile
[mn,fs] = audioread('xaudio.wav');
fc = 11000;
dt = 1/fs;
t=0:dt:(length(mn)*dt)-dt;
plot(t,mn);
%resample at 5k to get audio file below carrier freq.
[P,Q] = rat(5000/fs);
abs(P/Q*fs-5000);
xnew=resample(mn,P,Q);
P44100 = audioplayer(mn,44100);
P5000 = audioplayer(xnew,5000);
%play(P44100)
%play(P5000)
figure
dt_new=1/5000;
tnew=0:dt_new:(length(xnew)*dt_new)-dt_new;
plot(tnew,xnew);
