Midterm
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)
