I think this is my mistake -- as someone else pointed out, it should have been rzero_rev~, not rzero 1 -- sorry for the confusion. Miller On Fri, Apr 25, 2008 at 04:08:38PM +0100, Andy Farnell wrote: I've attached again an example of a patch that demonstrates the practical difference

Hello, For [z~ 1] you can use [rzero_rev~ 0] -- its response is: y[n] = -a[n] * x[n] + x[n-1] setting the coefficient to 0 gets rid of the current input and leaves the one-sample delay. Thanks, Matt Date: Fri, 25 Apr 2008 12:21:54 +0200 From: IOhannes m zm?lnig [EMAIL PROTECTED]
