If you find any of these videos of value, you will want to purchase this textbook to gain that fundamental understanding all engineers need to excel as designers.

Section 16.1: Differential TDR

In this video I introduce you to a differential TDR and what it really measures. 



Section 17.2: Tightly vs loosely coupled differential microstrip comparison video

In this video I answer the question, which is better, tightly or loosely coupled differential pairs.



Section 18.6: TDR measurement of diff pair with a large gap in the return path

What happens in a differential pair when the return path is removed from under the differential pair? See this analysis and measurement.



Section 19.3: Quite Universal Circuit Simulator (QUCS) source forge download link

Once again,hereis the link to download QUCS so you can play along at home with the experiments.


Section 19.4: QUCS chapter 19 examples ZIP archive

Here, you can download the simulation files for QUCS.


Walkthrough of QUCS example archive circuit files

Here I walk you through how to begin the process of hacking some interconnects using QUCS.



Section19.6: Circuit A walkthrough

In this video you will see how to model a discontinuity as a C, L or short transmission line and simulate these behaviors in QUCS.



Simple TR DUT hacking example

In this video, I show you how to hack a circuit model to match the measured TDR response from an interconnect. 



Section 19.9: Multiple TR DUT hacking example

Here, we will hack a more complex equivalent circuit model to match the simulation with a measure TDR response. This is how we use a TDR measurement to build a model of a discontinuity of the structure under test.



Section 19.12: Thru-hole axial lead resistor + TR line hacking model

Here, we hack a model for a real terminating resistor using the measured TDR response. Using this model we can evaluate the useful bandwidth for using this resistor.
