Vectors must be the same lengths.

Hi guys I am trying to add a white Gaussian noise to FM signal

this is my code fc = 20; %Carrier Frequency fs = 1000; %Signal Frequency t = 0:0.00001:0.002; x = 2*cos(2*pi*t)-3*sin(2*pi*2*t); dev = 50; y = fmmod(x,fc,fs,dev); r = awgn(x,10,'measured'); plot(t,[y r]) legend('Original Signal','Signal with AWGN')

but i got this error "Vectors must be the same lengths".

can you help me ?

Try this instead:

plot(t,[y; r])

The (;) creates a (2xN) matrix that plot will accept.
