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 12.3: Polar Instruments SI9000 commercial 2D field solver info site

Hereis a link to the polar instruments SI9000 tool, one of the simplest to use transmission line designers that uses a 2D field solver.


Polar Instruments SI9000 free 2-week evaluation license contact link. Here, you can request a 2 week evaluation license to the polar tool to try it out.

Section 13.2: SI9000 design space mapping tutorial

Here, we explore design space to see how changing the dielectric thickness of a microstrip affects its characteristic impedance. This is the analysis of a design.



Section 14.2: Symmetrical stripline approximation online calculator

Thisis an example of another online impedance calculator.


Section 14.3: PCBway internet fab website

Thisis a link to a very popular PCB fab shop located in mainland China.


Section 15.3: Fundamental principle of differential impedance

I offer the best way of thinking about a differential pair and differential impedance. This will eliminate a lot of confusion you may have about differential pairs. 



Section 15.7: When one line is part of a differential pair

The original of the three different impedances one line has that is also in a differential pairs is identified in this video. Remember, the essential principles are covered in the textbook.



Section 15.8: Odd mode impedance

Here we see the origin of the odd mode impedance of a line that is part of a pair.



Section 15.9: A common signal

Here we see the impedance of one line in a pair when the pair is driven with a common signal. This is the origin of the even mode impedance.
