1) Quiz 1 Logistics

Quiz 1 will take place on Tuesday, September 30 from 2:05 to 3:55 PM (i.e., the regularly-scheduled class hours) in Walker Memorial (50-340).

  • The quiz covers content from lectures and recitations up to (and including) September 18 and Homework 3.
  • The quiz will be administered on paper, so be sure to bring a pencil. (We'll have spare pencils on hand, but probably not enough for everyone.)
  • You may use one 8.5"-by-11.0" page (two sides) of handwritten notes.
  • To prepare for the quiz, we recommend that you review content from the relevant lectures, recitations, and homeworks; prepare your sheet of handwritten notes; and take the practice quiz under authentic quiz conditions. (Print out the quiz and take it in a quiet environment where you can focus. Time yourself. Use only your handwritten notes as a reference.)

2) Review Session and Resources

Alonso, Amy, Grace, and Titus will run a review session on Sunday, September 28 from 1:00 to 3:00 PM in 4-370.

  • The review session is more like a two-hour recitation than a two-hour lecture. The review session will emphasize practical problem-solving strategies.
  • The review session will not be recorded, but notes will be posted afterwards. We cannot promise that these notes will be a perfect substitute for attending the review session in person.

Here are the objectives for the review session.

  • Get the "big idea" of Fourier representations.
  • Curb the tedium of complex calculations using Euler's formula.
  • Determine Fourier series coefficients without computing integrals or sums.
  • Eliminate tedious calculations by remembering common Fourier transform pairs and properties.
  • Apply geometric reasoning to sketch magnitude and phase plots.
  • Understand how to sample continuous-time (CT) signals to generate discrete-time (DT) signals.
  • Recognize when aliasing occurs, how aliasing "folds" frequencies in a signal, and how to prevent aliasing.

Titus has provided a "story sheet" that you might find useful as you study for the upcoming quiz.

Here are notes and practice problems from the review session.
