Could an explanation of the term "pole" as used in the context of IIR be added to Wilkipedia? Existing definitions of pole don't help.

dropping the "Truncated IIR filter" section
I've deleted the Truncated IIR filter section. The author had confused the concept of the infinitely long output of IIR filters with some concern that the filter representation itself was somehow infinite and thus needed to be clipped. To which I say:
filter[0] = 10; for (tt=1; tt>0; tt++) { filter[tt] = 0.5 * filter[tt-1]};
There, that wasn't so bad was it? Fits on one line.
To confuse matters, google does show there is an obscure filter somebody has wickedly (or cleverly) called a "Truncated IIR filter", but it actually is an FIR filter. If someone wants to write a separate wikipedia article on that filter (along with the text explaining why it isn't really an IIR filter, and what purpose the filter serves, etc.) that would of course be great & we could add a "See Also" link to it, but it doesn't merit its own section in the main IIR article. technopilgrim 21:47, 13 Apr 2005 (UTC)
