Grading format:
Similar to the grading format of HW1, HW2 is graded for completeness as well as theoretical understanding of course material.
Comments:
- In Q2, $ (-1)^n = e^{j\pi n} $.
- When computing the DTFT using the summation formula, note that some expressions are in the form of geometric series.
- In Q3, convolution must be separated into various cases. The analytical expression will vary depending on the case. Also, drawing the signals is very helpful.
