Passive and Active Filters: Theory and Implementations

Here is a unified, modern treatment of analog filter design techniques. It covers both classical passive filters and RC active filters where the usefulness of the operational amplifier is emphasized. Topics are arranged to reinforce one another, and theory is supplemented and illustrated by numerous practical examples. Major focus is given to basic concepts, modern design techniques and implementation procedures. The text includes material on the design of broadband matching networks and compatible impedances; these topics are normally excluded from undergraduate curricula, but recent advances make their inclusion important.
