Hi guys, I'm having some problems with the discrete Transfer Function block. I'm trying to recreate the TF behavior I'm getting from Matlab, but I'm nowhere near. I have tried using both the Polynomial and the Poles and Zeros option to enter the values, but the output remains the same. z^4 - 3.753 z^3 + 5.272 z^2 - 3.286 z + 0.7666 / 4.421e-07 z^4 - 4.333e-07 z^3 I've attached my Embed file, that contains the Reference and the TF blocks. I've also included a couple of screenshots from Matlab that show the behavior I'd like to obtain from Embed. I've made sure that Embed and Matlab have the same Time Step, which you'll be able to see from the reference input (it's the same on both softwares). I don't know what else to do, I really hope you can help me out. Bezier_test.vsm

Submitted by benl on Mon, 01/30/2012 - 19:39 I'd like to find the time derivative of a measured input signal to a F28069 Piccolo. Is there a standard fixed-point solution for this? Many thanks, Ben
