Help : Books on Active Filters?

[Izzy]

Hey guys , I was trying to buy a book on active filters, so I looked in half.com and they had lots of them.
But do you guys know any good one?

I dont want to go really deep in theory and I dont want to pay too much.
I found some cheap ones but they were like published 30 years ago. Does that make in difference?

Any recommendation?

The best book ever writen on active filters was written about 30 years ago - The Active Filter Cookbook by Don Lancaster.

Practical Electronic Filters by Owen Bishop is another good Book.  Easy to read and packed with info. 

The explanations can be a little sketchy at times but I found the stuff on 'knees' (though I think he uses different terminology) and the types of responses easy to grasp.

Babani publishing.  Cheap but worth a read.

Seconded! For working knowledge, it's great. And easy to swallow.

I've been meaning to pick up the Lancaster book for a while, but it's come *very* highly recommended to me from people online and in the "real world".

The trouble with filters, for those of us who aren't EEs, is that really, there is no way to avoid maths. Even if one is using a 'snip & paste' strategy - a bit of that circuit, a bit of this circuit - filters can be tricky. For example, the behavior of a filter can (and probably will!) change dramatically depending on the impedances of the source feeding it, and the load it drives.

On the subject of books, here's one that assumes the reader is an EE student, but is very much practically oriented, with emphasis on real-world problems (including imperfect op-amps). Anyone with the run of a uni library might want to check it:
Van Valkenburg "Analog Filter Design" Saunders 1982. Assumes knowlege of Laplace transforms, but I still had a happy browse.

I am an EE student, but not at that level that I can understand anything.I am sophmore, so I am like a begineer. Actually Electronic I, is going start from this semester. May be after this smester I will be able to grasp some.
But yes thanks for the recommendation. I will try to grab one.
