RE: [SI-LIST] : TDR Analysis: Layer Peeling Algorithm using Matlab

Hello, Christian:

It's really great that you published the Matlab implementation of the =
peeling algorithm. However, your Matlab file states that the reflected =
waveform must not be a superposition of incident and reflected, which is =
normally the case for TDR instrumentation, and it is not a trivial =
timing task to separate the two. What kind of instrumentation do you =
guys use, and how do you achieve this separation?

Thanks,

-Dima

Hi there,

it's some time ago that the extraction of impedance profiles
from TDR measurements was discussed and several references in=20
literature were given. If somebody is still interested:=20
I implemented one of these algorithms in Matlab code and it's
downloadable from my web page given below. At our institute
we use it for parameter extraction from FDTD simulation results
of interconnects.
