1. Problem 8.1.

2. Problem 8.4.

3. Problem 8.14. Be sure to show your work. In addition, use MATLAB's fft and ifft functions to do the convolution -- i.e., take the N-point DFT of x₁[n] and x₂[n], multiptly them together, and take the inverse DFT of the answer. Show x₃[2] is the same using both methods.

4. Problem 8.17. In addition, use MATLAB's fft and ifft functions to do the convolution -- i.e., take the N-point DFT of x₁[n] and x₂[n], multiptly them together, and take the inverse DFT of the answer.

5. Problem 8.27. You may use MATLAB to do the convolutions.

6. Problem 8.43.
