how to add noise to image matlab

N=200;
T=0.05;
t=(0:N-1)*T;
s=sin(2*pi*120*t);
subplot(3,1,1),plot(t,s);
fft_s=fft(s);
subplot(3,1,2),plot(t,real(fft_s));
subplot(3,1,3),plot(t,imag(fft_s));
this programme relates to bearings, so how to add noise to this programme. noise should relate to the faulty bearings from the machine.

Thanks.....

If you have questions for the same post, please ask them in the same post. If you keep on creating new posts for similar questions, people would get fed up and no one would help. Maybe you are new to this forum. But be advised.

Secondly, for the type of questions you are asking, open Matlab, go to help for Communication Tool boxt. There are tutorials for beginners.
