Active-Filter Cookbook

Description

This book is about active filters. It is user-oriented. It tells you everything you need to know to build active filters, and does so with an absolute minimum of math or obscure theory. If you know nothing at all about active filters and simply need a frequency-selective circuit, this book will serve you as a catalog of ripoff circuits that are ready for immediate use—with math ranging from none at all to one or two simple multiplications. If you are interested in the how and why of active filters, there is more-detailed information here that lets you do more-involved design work, optimizing things to your particular needs and perhaps using a simple handheld calculator for the actual final design effort. Finally, if you are an active-filter specialist, you will find in this text a unified and detailed base that includes both analysis and synthesis techniques that can be easily expanded on by using a computer or programmable calculator. This book should be extremely useful as a college-level active-filter course book or supplemental text.
