Implement the following Matlab code:
x=zeros(10,128);
t1=[0:1/128:1-1/128];
z=cos(2*pi*2*t1);
x(1,:)=z;
x=reshape(x,1,1280);
figure(1);
plot(x)
Examine Figure 1 – what does it “look like”? Zoom in. Take the FFT of x and explain what you see.
Manipulate the FFT and perform the IFFT to create a signal which is a continuous (i. e. no interpolating zeroes) sinusoid in the “time” domain. Explain the amplitude of the sinusoid.
