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 (so do not worry about including these on your cheat sheet).
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
- AM modulation/demodulation; Single-sideband AM
- Laplace transform and ROC's
- Z transform and ROC's
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)
