Hello Ryan,
I am referring to the first edition of the book:
chapter 3.6.3 (Influence of Series Resistance on TDR Measurements), pp.
169-173
chapter 3.7.3 (Influence of Skin-Effect on TDR Measurements), pp. 188-189
The first section even gives an example calculation of the impedance
slope.
Best regards,
Wolfgang

Re: TDR Measurement of a Long PCB Trace - Increased value over time
Hello Wolfgang-
Thanks for your prompt response on my question. Your explanation is
helpful. I have Dr. Johnson's book and have read it at least once, but
cannot find where he discusses this. Can you please direct me to where he
references this phenomena?
Regards,
Ryan Satrom
