I often need an arithmetically symetrical filter. I have used Sfilter with some success.
Recently I came across an article in March 1964 IEEE Transactions on Circuit Theory with the interesting title;
"A Group of Arithmetically Symmetrical Band-Pass Filter Functions"
It may be a useful addition to your software.
If you need a copy please let me know.
Thanks for your excellent product.
