Obviously the workload and difficulty are relative to the student. The only work we did was doing the lab and writing up the lab reports. You have to answer some questions in your report that are in the lab instructions. So I felt the workload to be really light.

The coursework isn't that hard to be honest. In the 1st half of the course, he lectures about the synthesis and analysis equations of the Fourier transform and its inverse; for continuous time and discrete time. Reviews nyquist plots and throws out whatever you learned in 171A out the window. You learn how to do controller design in the frequency domain, very handy tool. What was awesome was reconstructing plant models from random signals, as well as from white noise; very powerful. You learn about cross-correlations and auto-correlations.

Since a lot of grad students were also in the class, he introduced material towards the end of class that were at the "grad" level. Honestly it wasn't that hard, I just wish I had a better linear algebra instructor so that I can remember singular value decomposition and etc. But it wasn't hard to follow.
