Name: UIN: Course No 4. (20 points, 5 points each) Two finite length signals, nijej and rlel are given Let

The matlab code is given below, Read the comments and execute in the command window

%signal 1
x1= [1 1 1 1 1]
%signal2
x2=[1 1 1 1 1 1 1 1]
%linear convolution of x1 and x2
y=conv(x1,x2)
%8-point circular convolution of x1 and x2
y1=ifft((fft(x1,8).*fft(x2,8)),8)
