The material here is mostly based on the chapters 5 (SISO systems) and 6 (MIMO systems) of [1].

While the treatment of the book is more than sufficient for our course, we list here some other resources for further reading. The popular paper [2] provides a nice explanation of the waterbed effect(s).

Interested readers may want to consult the specialized monograph [3], but it is certainly not necessary for our course.

More recent results are surveyed in [4].
