Zverev is the classic reference for continuous time filter design, especially lumped element LC ladder filters. The book is mostly tables, but the plots of filter behaviour for different designs--ripple, group delay, and so on, are easily worth the price. The discussion of how to synthesize a bandpass, bandpass, or bandstop filter from a lowpass prototype is very useful. They don't teach this stuff in school any more!

This is the bible of filter design! Complete and in-depth coverage of the theory and design of filters. I use this book primarily for the tables but the coverage in the early chapters is essential reading for any filter designer. This is an indispensible text book and I highly recommend it.

The Zverev's handbook is must for filter design. Probably one of the best books available on the market. The helicoil filter chapter is quite well done. It is little bit hard-to-navigate through. Definitely it is not book for beginners. You will find answers no software can offer.

No doubt about it, this is the universally cited filter reference for good reason! Plenty of information on LC filters that can't readily be found elsewhere in one place; plus pretty nearly all the essential background you need to synthesize active filters as well, even though you have to extrapolate a lot of the latter for yourself. To a certain extent, that's to be expected with this book. All the principles it teaches are stated in concise and condensed form anyway, and you have to read carefully to absorb it all. That's fine. But this is also where the shortcomings begin to crop up with regard to newer filter techniques.

One of my few disappointments with this book is that the publisher advertises it as "Revised" in 2005. They seem to have a rather more optimistic definition of the term than I do. Active filters are mentioned briefly as the coming thing, while there's one single paragraph on switched-capacitor filtering and NO treatment of any other sampled filters. If the words "digital" or even "discrete" appear anywhere in the book at all, I have yet to find them.) Although I am now officially an old geezer, I do seem to recall active filters and DSP being relatively mature technologies by 2005! The content of this volume, however, is still stuck firmly in 1967. That's not a bad thing by itself--the fundamentals of filters have not changed. But if you're you're going to call a book "revised," surely it would have been just as well to omit such glaringly outdated passages entirely and refer the reader to whatever newer works may now exist which treat these subjects at a level comparable to Zverev's own.

My second worry is how durable this paperback edition is going to be. The paper quality is fine, but the binding inspires no confidence. The printing is also not up to the quality of the original hardcover. My impression--strictly based on my own rosey nearly-45-year recollection of the first edition--is that some figures, such as the extensive schematics and math of the different filter configurations in Chapter 1, have been further shrunk to fit the page format of this edition. Some of the equations they contain are definitely hard to read even with a magnifying glass; not that they are blurred, but some of the characters appear to have filled in a bit in this reproduction.

Those are quibbles that mainly spring to mind when I consider the price of this volume, but I gave it four stars and recommend it to prospective purchasers none the less...particularly to students and working engineers. The information contained therein still belongs on the bookshelf of anyone doing filter design. You WILL need more books than this one nowadays, but it remains just as essential a grounding in the subject as it was in 1967.

Zverev is the seminal work in analog filter design. I have found it especially useful in the design of image-parameter filters, which are not covered in most modern texts. These types of filters predate modern filter theory, which is based on polynomial analysis. Image parameter filters, A. K. A. Zobel filters, are based on transmission line theory. In some applications, they out-perform other styles.

The book has plenty of polynomial designs, and all the usual types are included: Butterworth, Chebychev, Bessel, Legendre, Cauer, etc. Many filter and network transformations are also included: Low-pass to high-pass, low-pass to bandpass, lattice to ladder, t-section to pi-section to half-section to full-section, lattice to bridged-T, coil-saving transformations, I could run-on for pages.

There are tables for every type of filter covered, up to 7-10th order. These give pole/zero positions and normalized L-C values for passive filters. This is a fairly large-format book, and there are lots of response curves, which are large enough to be useful for estimating reponses. Reproductions of these curves have been in small format books, where the curves are not large enough to be very useful.

Not covered: Active analog filters, and digital filters.

I purchased for the tables every other author cites. The theory is wonderful and fills in the many gaps in other texts. Many of my assumptions have been confirmed or not. The math is sometimes unwieldy yet is accessible to even a math-neophyte as myself. They should teach this stuff in High School.

Great book ! Ultra precise (but not so concise)
A must: ALL filters type & theory are here, with extensible tables, tricks etc..
As someone said: not for the beginners !
(i could recommand for them the Arthur William "Elec. Design Filter Handbook"= LessTheory +ActiveFilters topology)
