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)
