The 7th TSEI50 lecture is taking place tomorrow morning. I will arrive slightly late due to some children daycare issues. Hope to be there at 8.25. The lecture will discuss stability and other properties of the z-transform, and how it relates to the frequency response of a system.
I have also found the exams from the last few years and plan to add them to the home page shortly.
Tomorrow is also the first lab, please be as prepared as you can be before going there!
