Kari,

 There is an application of an FIR filter in the applications data
 book from Microchip.  Not sure what number it is, but is probably
 on the website too.   I used this to write a filter program for a
 CW filter for Ham Radio Applications using the 16C84 at first, and
 then the 17C42.  It worked well, but not as good as a dedicated DSP
 chip obviously.


                                                Regards,

                                                  Jim
