What is an ideal quadrature filter? Why can't it have finite support? —Preceding unsigned comment added by 163.1.84.1 (talk) 15:02, 14 November 2008 (UTC)[reply]
Is this a complex valued signal of a real variable?[edit]
If so I can't fathom what putting in the Dirac is supposed to mean. will simply be 0 except for t = 0. Typically in signal processing stands for a real variable, so that seems needlessly confusing. I don't see why wouldn't be better.
This article needs to be completely re-written with sources and definitions, otherwise it's basically just noise. The original author(s) seem to have abandoned it. 2601:647:C900:B6C0:4DB5:BC5:AC2D:5F93 (talk) 20:31, 29 December 2022 (UTC)[reply]
