Lecture 15 Blog, ECE438 Fall 2011, Prof. Boutin

Monday September 26, 2011 (Week 6) - See Course Outline.

Today we obtain the relationship between the CTFT of a finite duration signal and the Discrete Fourier Transform of its periodic repetition.

Relevant Rhea pages

• A page about the DFT written by a student
• Recommended exercises of Fourier series computations for DT signals (to brush up on Fourier series))

Action items

• Keep working on the third homework
• Everybody should add at least one formula to our DFT table.
• Keep working on the two DFT practice problems (and share your answers)
  • Compute this DFT
  • Compute this other DFT
