Hello Dirk et. al.,

There is a book "Digital Signal Processing - Theory, Design, and
Implementation" by Abraham Peled and Bede Liu, 1976, that has some info on
decimation and interpolation with FIR filters. They present several worked
out examples as well as give some theory. Even though the book is rather
small, 304 pages, it presents some pretty neat ideas.

Seems like there was a book about this (or including this) out in the early
80's by Bede and Lui (could be spelled wrong).

Ellegaard, You might Google on "lookup table filter FIR" to get things like this: http://www.chipcenter.com/dsp/DSP000301F1.html Fred

Hi Ellegaard,

Chances are that what you are looking for is the distributed arithmetic (DA) 
algorithm. Google for it and you should find a plethora of information.

Hi,

Currently I am using a polyphase FIR filter to perform an
interpolation. To gain performance I have in mind to redesign the
original filter with the principle of a lookup table. Does anyone know
where I can find some helpful information of how to implement this
principle?

Regards,
Ellegaard
