Quiz Solutions
Quiz 1 Solution. Mean = 13.00 (out of 20), Standard Deviation = 4.62.
Quiz 2 Solution. Mean = 10.06 (out of 20), Standard Deviation = 5.14.
Quiz 3 Solution. Mean = 11.23 (out of 20), Standard Deviation = 3.96.
Quiz 4 Solution. Mean = 18.24 (out of 20), Standard Deviation = 2.28.
Final
Schedule: The Final is scheduled to be held Wednesday, August 5, 8-10AM in EE117 (the lecture room)
Policy: No calculators are allowed on the exam, but you will be allowed one 8.5"x11" sheet (front and back) of hand-written notes. You will be given important portions of book tables 4.1, 4.2, 5.1, and 5.2 on the exam.
Coverage: The exam will cover all material covered since the Midterm (including CT Fourier Transform). A list of topics include
- CT Fourier Transform
- CTFT properties and use of the tables (included on the exam)
- DT Fourier Transform
- DTFT properties and use of the tables (included on the exam)
- Differential/difference equations for DT/CT LTI systems computed via Fourier transform
- Nyquist Sampling Theorem/Sampling/Aliasing
- DT implementation of CT systems/filters
- AM modulation/demodulation; Single-sideband AM
- Laplace transform and ROC's
- Z transform and ROC's
Preparation: Reviewing the previous quizzes and homework are good ways to prepare. What I've assigned and quizzed on in the past suggests what I will emphasize on the exam. Also the practice exams below, given in past semesters by other instructors, will be good practice, though may not necessarily reflect our exam.
- Practice Final 1 (no solutions)
- Practice Final 2 (with solutions here)
- Practice Final 3 (with solutions here)

Midterm
Midterm Results: Mean = 64.61 (out of 100), Standard Deviation = 15.31.
Policy: No calculators are allowed on the exam, but you will be allowed one 8.5"x11" sheet (front and back) of hand-written notes.
Coverage: The exam will cover all material through lecture on Wednesday, July 8. Thursday and Friday's lecture will review exam material. The topics include
- Signal properties (even/odd, periodicity, power, energy, etc.)
- Independent variable operations (time shift/scaling/reversal, etc.)
- System properties (Memoryless, causality, time-invariance, linearity, stability, invertibility)
- Finding System properties of LTI systems from properties of the impulse response
- DT and CT LTI system input/output relationship by convolution
- Differential/difference equations to describe LTI systems
- Fourier series of DT and CT periodic signals and Fourier series properties
- Fourier series of output of an LTI system
- Continuous Time Fourier transform (CTFT) and CTFT properties
Preparation: Reviewing the previous quizzes and homework are good ways to prepare. What I've assigned and quizzed on in the past suggests what I will emphasize on the exam. Also the practice exams below, given in past semesters by other instructors, will be good practice, though may not necessarily reflect our exam.
- Practice Midterm 1 (no solutions)
- Practice Midterm 2 (with solutions)
- Practice Midterm 3 (with solutions here)
