All, Mea Culpa, my critique of the Crosstalk BIRD last week was incorrect. After a careful read I totally agree with the contents of the BIRD and would support a motion to submit it to the Open Forum, with this committees concurrence. Not for Naught! I did document an example of a coupled system containing a single victim channel and two aggressor channels. The various elements of the Impulse Response are defined using Touchstone notation, and the input and output of the impulse response matrix for each Tx and Rx AMI_Init function call is defined by rows and columns in the differential mode, coupled sNp that represents any coupled channel. I would like this document posted, and I would like the weekly minutes to note it. Walter Walter Katz wkatz@xxxxxxxxxx Phone 303.449-2308 Mobile 303.883-2120
