EE 313 Linear Systems and Signals - Lecture 6

Lecture

• Lecture slides on the Sampling Theorem in PowerPoint format.
  • Lecture notes: Part 1 - Part 2 - Part 3
  • Demo. "Amazing Water & Sound Experiment #2" which shows three different examples of aliasing due to sampling.
  • Demo. Sampling and interpolation to show sampling of a sinusoidal signal and how the reconstructed signal quality depends on the sampling rate and the choice of pulse shape
  • Handout. Handout D Discrete-Time Periodicity,
