COURSE OBJECTIVES: When a student completes this course, s/he should be able to:

  1. Design linear discrete-time systems and filters and analyze their behavior.
  2. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous time when necessary.
  3. Compute approximations to Fourier transforms of continuous-time signals with finite discrete time methods.
  4. Take advanced courses in signal processing (image, speech, audio, etc.), communications, systems and control.
