Designing and Building Electronic Filters

Filters are a fundamental part of any electronic circuit, and they are used in virtually every electronics application and system. This book aims to provide electronic hobbyists with a complete workbench guide to these important components. Entirely practical in its presentation, with a minimum of theory and maths, this book covers all kinds of filters: low-, high- and band-pass; band-reject; state-variable; voltage-controlled; and digital. Each chapter focuses on a single filter type, presenting its characteristics, uses, specifications and substitution values. Thirteen easy-to-follow projects show how to build a variety of practical filters, all of which use real-world component values in order that readers can easily implement them in their own designs.
