The ability to quickly put together a working filter is a must for any practicioner of electronics. Unfortunately, current technical training has joined the rush to computerize, emphasizing digital circuitry at the expense of analog circuit design. As a result, many trained electronics technicians lack basic skills in simple filter design. This book shows hobbyists, technicians, and engineers how to design and build practical filter circuits, using simple mathematics and straightforward procedures. Readers will learn the difference between real-world and "textbook" filters (discovering why filter designers are so often led astray by the mathematical texts now used), and they'll learn how they can avoid falling into the same trap with their own filter designs.
I was surprised at what could be accomplished with just different combinations of inductors and capacitors!This is a neat book at teaching the concept.. plus you can build all kinds of neat filters!
