[sdiy] Digital interpolation filtering

[Neil Johnson]

Tom,

Please try out the page at York.  Here's the URL again:

       http://www-users.cs.york.ac.uk/~fisher/mkfilter/

You could start with a raised-cosine FIR filter, and you can also  
specify truncating the filter to 16 bit data.

It will give you back C code, plus graphs of responses.

A very useful page.

Cheers,
Neil
