Final

Final Solution If you would like to pick up your graded Final, you may drop by Landis' office after August 9 (or send an email if he is out).

Final Results: Mean = 77.95 (out of 120), Standard Deviation = 17.52. 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.

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.
