Midterm
Midterm Results: Mean = 64.61, standard dev. = 15.31. The midterm will be held in class Monday, July 13. (Note that there will be no quiz on Friday, July 10, but there will be one Friday, July 17).
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)
