EECE 402 Digital Signal Processing                                              

News & Announcements

• The course EECE 402 is offered as a technical elective in BU's ECE Department.
• It is cross-listed with EECE 520, which is intended for graduate students who have not had a DSP course
• It is expected that you have had a solid Signals & Systems course
  • We cover some of the same topics (e.g., ZT, DTFT, Sampling, DT Filters) but we do so at a deeper level

Textbook

• The material here is based on the following textbook

  • John G. Proakis and Dimitris G. Manolakis, Digital Signal Processing: Principles, Algorithms, and Applications, 4^th Edition. Prentice Hall. 2007.

• Material in Note Sets 22 - 24 are based on Ch. 6 from B.  Porat, A Course in Digital Signal Processing, Wiley, 1997.
