Why not drop the author an email and ask? You might just get some help as long as you don't ask for code or patented material. There is a contact email address on this page: http://www.kvaleberg.com/ Apart from that, the most comprehensive description of the Remez algorithm that I have found, is in this book: http://www.amazon.com/gp/product/0071454241/sr=8-1/qid=1146128224/ref=sr_1_1/103-8032747-6359858?%5Fencoding=UTF8 Rune

LOL .. Anyways Jerry I will give a more nice explanation to what I was asking later on .. Please do not forget me.

I didn't know the language and had no idea that it had become common enough to be googled. What I see, "a quick-easy-dirty fix or a resource that can be used as such or a person who can suggest, conjure or implement a quick-easy-dirty fix" does not exactly match what I believe my sig to mean. I do see a connection. Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������

Well you could always look up 'jugaad' in google . Its usually the first search result.

The *only* reason I can think of to run Remez in a DSP would be if you somehow created a sort of adaptive filter that would generate the necessary frequency response as an interim "output" - that could be used to develop new designs in "real time" so to speak. One example would be if you want to force absolute zeros in a stopband and would use the Modified Remez Algorithm with the Generalized Sign Alternation Property. All you need to know are the general filter characteristics and the location of the desired zeros and have the expectation that the location of the desired zeros will be changing and you'll know the *new* locations. I have *never* seen this done. I suppose it's because those interim zero locations or filter responses are generally not known! But, I think it would be cool because I know the guy who developed that Modified Remez Algorithm. I think the adaptive filter algorithms are probably better for this type of application. Fred

That's an astounding degree of compression! Is there another way to translate 'jugaad'?

Sorry Jerry .. The problem seems to be on my side . Yes my assumptions maybe wrong. I will tell you exactly in a day or two . BTW ... the term for 'Engineering is the art of making what you want from things you can get.' in our language is 'Jugaad' ;) Thanx Jerry Bye
