Not too easy. Not too difficult.
I would recommend it because the professor sort of makes you learn, but on the other hand he has a tendency of slowing down the lecture by pausing for the smallest distractions that don't even bother anyone.
The highlights of the course was today's lecture when a different professor was a substitute and he taught in a way that was clear and only stopped lecture for questions rather than getting mad at someone. I learned that the moments of expectation can be related back to signals and systems.

Advice for students:
Be sure to do the homework ahead of time, because it is tedious and the professor assigns many problems. Also, even though it may seem easy at the beginning, study all the properties for the midterms and other exams, because it is easy to underestimate the exams.
