Course focuses on the theory, representation, and processing of signals and systems. Continuation of ECE212 — Circuit Analysis. Followed by ECE311 — Introduction to Control Systems. Laboratory work is done in MATLAB and Simulink.
No textbook, but a few resources stand out:
- Class notes by Prof Simpson-Porco
- Video lectures and textbook by Prof Alan V. Oppenheim (MIT)
