Hello, This note is about Zverev's book "Handbook of Filter Synthesis".
As far as I know, there was only one edition. If there was a second, then perhaps the errors were corrected. Maybe there is an errata-sheet available But, if one is buying the first edition, be aware that the book is full of mistakes. Three things that come to mind most notably are: 1. the section on band-reject filters. 2. element values for the Cauer designs did not match up to the gold-standard I used; it is regrettable that I cannot recall the name of that book (maybe by Telefunken) because it has been almost twenty years since I used it; personally, I would not trust any Cauer values from Zverev. 3. toward the end of Zverev, his chapter on network transformations (equivalent circuits) has issues as well. I used Zverev from 1970 to 1997 and marked-up in red pencil the mistakes concerning designs on an "as needed" basis. Usually the mistakes were encountered while under a pressure deadline to get a quote out quickly. Not that it probably matters now-a-days but, if you wanted to make a n=6 or n=8 0.05 degree phase-ripple crystal-filter, Zverev does not have it. Zverev's style of writing was to take a simple task and write it up as incredibly complicated as can humanly be done; just my opinion. 73 Jerry KM3K ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
