Introduction to Electronic Filters
This chapter is devoted to the basics of electronic filters. Although it is primarily for readers who are totally unfamiliar with filters, it is also very helpful for readers who need a refresher. As you may already know, traditional filter design involves mathematics. Complex algebra is used extensively in filter-design equations and to represent filter functions. However, it is possible to design filters using simple equations. In many cases, filter design can be further simplified by means of tables, charts, and graphs. This is the approach taken in this book. Math is kept to an absolute minimum. So before we get into the practical step-by-step details, let us establish some basic terms found in ...
