Fundamental Limitations in Filtering and Control

This book deals with the issue of fundamental limitations in ltering and control system design. This issue lies at the very heart of feedback theory since it reveals what is achievable, and conversely what is not achievable, in feedback systems. The subject has a rich history beginning with the seminal work of Bode during the 1940's and as subsequently published in his well-known book Feedback Amplier Design (Van Nostrand, 1945). An interesting fact is that, although Bode's book is now fty years old, it is still extensively quoted. This is supported by a science citation count which remains comparable with the best contemporary texts on control theory.
