Forthis task, generate some data sampled at 500 Hz. Form a signal containing a) 30 Hzsinusoidal signal with an amplitude of 5
b) 100 Hzsinusoidal signal with an amplitude of 2
c) Zero-mean random noise with a standard deviation of 1. The length of your data shall be 1 second
CODE:
t=0:0.0005:1.0;
y=sin(2*pi*30*t)+sin(2*pi*100*t);
y=y+2*randn(size(t));

Hi George Rodriguez,
It is my understanding that you want to analyze a composite signal i.e., sum of different frequency signals. You can do it using "fft". You may find this answer helpful.
