stupid way: the coefficients are called "fb1" and "fb2"; "fb" is an abbreviation for "feedback", so this might have put you onto the right track. complicated way: "last" and "prev" refer to past output samples (as has been mentioned in other emails), and using old output to generate new output is the definition of feedback. fgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Icedove - http://www.enigmail.net/ iQIcBAEBCAAGBQJTS41zAAoJELZQGcR/ejb4oeQP/3+xpmUWOzSOH/f7a/jfc/zd X5BZLKN+4aCyJYcV1UIHvCE5qwlxJEtbP1c1bdh60VkIpHbKWGY4/S7kUOMRdpS7 Q3HewMDZ/o21YqKTjvPWgu+/hs72EcjG3kn9ZuE7SaiO3fIOhyd81kl/nCkrUH1H m6rlcedEvFg1Gdz7CaN9WyfoIN53MgQAFnKOKO/mQplLN50kGhXL7cXJrPa9qdIQ /k7m4xAuU28oxWvDWnQk2OUB7mTBm0crOrwpCt+cV3lrc/lrbIr3syyUP6cPkPoO xgAJaqA4l3w3maMI5oCSN/8gaOiROmInVYYEntBtyPowKnku4su7FRj5ueBNA5XW WheIeYjcNDseVpciTOOUdRPzFgcEfRxsWbuuL38iSdUdxqaqxwdqiu/zhyVpVh4l XCXJV0prsMvZbCxO56myt/rglZEVC0LhFWoPqkKxXBSe8JSgLfokx1x7mrFkha4m X347sw/KHjdkeQR8NXnNLSuHNRmC7rWwiBf7JZizNbSWgQJpxP9tcMLoY7PHJz3C 6M5uhBnjW13kSokPBITZLsV2x3uZkNbe0zgaUVDTgWDglGvk9hkZLPzxnXapdjw6 c4O9oaaRhslyyN9nspvZn+g6Xe9omHuJWaIWafsB71pupJ9P0fyad/a80TV0yMYz W3YkO5lYRXesKfjm+Iiu =w5cg -----END PGP SIGNATURE----- _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
