Preface
The purpose of M athematics for Circuits and Filters is to provide in a single volume a comprehensive
reference work covering the broad spectrum of mathematics and symbols that underlie numerous
applications i n e lectrical c ircuits and filters. It i s written a nd d eveloped for practicing e lectrical e ngineers
in industry, government, and academia. Over the years, the mathematical fundamentals of electrical
circuits and filters have evolved to include a wide range of topics and a broad range of practice. To
encompass s uch a w ide range o f k nowledge, the b ook f ocuses on t he k ey c oncepts, m odels, and e quations
that enable the electrical engineer to analyze, design, and predict the behavior of l arge-scale circuits,
devices, filters, and systems.
