About this subject
Prepare basic signal operations (scaling, shifting, addition, multiplication), inverse Z-transform by partial fractions, Laplace ROC with properties, and sampling/first-order hold. Shared with KU BTEE305: basic signal operations (KU C1), mechanical system models (KU B1) and Fourier transform/DTFS basics, so one revision of these covers both papers.

Anyone else finding Signals and Systems tricky? 😅
Lesson 2 cleared it up for me. Watch it before the quiz
Doing it now, thanks!
