USING MATLAB CODE PLEASE...

1.Design a bandpass filter to only pass through the signal with a frequency of f1-f2 and show how your filtered data look like.

Given the following code:

f1=100.02; f2=100.00; t=1:100;

ysignal=1+.1*cos(2*pi*f1*t); A=fft(ysignal); plot(t,A,'r')%figure1

yreference=1+cos(2*pi*f2*t); B=fft(yreference); figure plot(t,B,'r')%figure2

C=fft(ysignal.*yreference); figure plot(t,C,'r')%figure3
