  • Note: If you have an older version of the Homework 2 Solution, note the following: Page 6, 5e, u[-n] should be u[n]. Page 7, 6a, u-k=n should be u-k=m. These are updated on the currently posted solution.

• Note: HW 7, P. 1: Write the error expression as a function of a and (atilde - a). The goal is to understand how the signal reconstruction error E depends on the channel estimation error (atilde - a) P. 4(b): Assume that x(t) is not only band-limited, but in fact: X(j omega) = 0, |omega| < W_0 and |omega| > W, where W_0 < W, and that |X(j omega)| < infinity for all omega. Then, show that the modulating signal, y(t) = integral_{- infinity}^{t} x(tau) d tau satisfies integral_{- infinity}^{infinity} |y(t)|^2 dt < infinity. This shows that "most of the time, the modulating signal y(t) must be bounded" (It may still have some large spikes, for very short durations, but in practice, this may be okay).

Exam information

• Sample Midterm
• Sample Midterm Solution
• Midterm 1 Solution
• Midterm 2 Solution Version A Midterm 2 Solution Version B There were two versions of Midterm 2 with different numerical values. Choose the key that matches your exam.
• Midterm 2 instructions:
  • General: By contrast to Midterm 1, where a sizeable portion of the points were given for getting the exact result, Midterm 2 will aim at assessing your understanding of the material and your ability to apply it to new situations. Your understanding of the material involves applying the right tools to the problem, but also such things as having meaningful mathematical formulae (integrals that converge, etc).
  • Midterm 2 focuses on Sampling and Communication Systems, i.e., Chapters 7 and 8 of OWN. However, it is assumed that you are familiar with Chapters 1-5.
  • Rules: The exam is CLOSED-BOOK CLOSED-NOTES. Calculators and other computing and communications devices are not permitted. However, you can bring 2 double-sided handwritten and NOT photocopied sheets (8 1/2 x 11). Moreover, you will receive tables 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 of the textbook.
  • There is no old Midterm 2 unfortunately. Instead, you may study the Midterms of other faculty (as available at HKN), and the following problems from the textbook: 7.10, 7.12, 7.17, 7.32, 7.43, 8.8, 8.9, 8.16, 8.31, 8.43. Remark: No written solutions will be provided for these problems. However, you may ask questions during the review session as well as during office hours.
• Final Exam instructions:
  • General: Similar to Midterm 2, the Final Exam will emphasize the correct application of concepts to different scenarios over getting every detail correct.
  • Coverage: The Final Exam covers all course materials up to the Butterworth filter design trick, according to the table below. Chapters and Sections that are not mentioned in the table need not be studied explicitly for the final exam. In particular, note that the Final Exam covers all of the four big topics of the class: sampling, communication systems, Laplace transforms, and z-Transforms.
  • Rules: The exam is CLOSED-BOOK CLOSED-NOTES. Calculators and other computing and communications devices are not permitted. However, you can bring 3 double-sided handwritten and NOT photocopied sheets (8 1/2 x 11). Moreover, you will receive tables 3.1, 3.2, 4.1, 4.2, 5.1, 5.2, 9.1, 9.2, 10.1, 10.2, 10.3 of the textbook.
  • In line with standard practice in the EE 12X series, the old final will not be made available. Instead, it is suggested to attempt the following problems: 7.13, 7.14, 7.15, 7.30, 7.31; 8.10, 8.18, 8.24, 8.35; 9.7, 9.16, 9.17, 9.27, 9.33, 9.51; 10.4, 10.11, 10.30, 10.36, 10.59. Remark: The solutions to some of these problems are given in the textbook. For the remaining problems, no written solutions will be provided, but you may ask questions during the review session as well as during office hours.
