4. DFT using the fft function in MATLAB: Compare both problems with their analogous Fourier Transform pairs. How are they alike and how are they different?

• Using an N=128 point DFT: generate x(n)=cos(2p k_c n/N) for n=0,1,….(N-1). Use k_c = 1 and 8. Plot x(n) and also plot the real part of fft(x). Repeat for x(n)=sin((2p k_c n/N), but, plot the imaginary part of X[k].
• Using an N=128 point DFT: generate x(n)=rect(n/33). Plot x(n) and also plot the real part of fft(x). For rect(n/33), in matlab indexing, x(1 through 17)=1, x(128-15 through 128)=1 and the rest are zero.
