So give or take a few LSB errors, are digital filters like filters in the analog domain?
Yes.
So if we have N digital poles, can we create N digital zeros at the same frequencies, convolve those two filters and arrive at a digital wire ? Of course there may be some delay here...
Yes.
Practical ?
Yes. Already done, as your EE eminence well knows.
Well, this week I was playing with my Lexicon AD convertors and a good microphone setup, driving my large monitoring system with my latest high quality ground-seperated 384 kHz DA convertor in a real-time situation, and wanted to compensate the small (few dBs here and there) the frequency sensitivity unevenness of the microphone I used, and applied some jack/jack-rack/ladspa Linux filters for that. Worked great.
But did it actually constitute a digital wire? -- Sampo Syreeni, aka decoy - de...@iki.fi, http://decoy.iki.fi/front +358-40-3255353, 025E D175 ABE5 027C 9494 EEB0 E090 8BA9 0509 85C2 -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
