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 4.5: The input impedance of a transmission line

This video explains what the input impedance of a transmission line and how a signal is launched as a voltage into a transmission line.


Section 5.2: The boundary conditions between two different transmission lines

I explain the conditions on the voltage and the current where two transmission lines connect. This is the basis of understanding why there are reflections.



Incident reflected and transmitted voltage and current

This video sets up the relationship for the currents and voltage in the two regions where two transmission lines meet. This is the next step to understand why there are reflections. 



Algebraic derivation of reflection and transmission coefficient

I answer the question why there are reflections and how we can calculate the reflection coefficient and the transmission coefficient, based on the boundary conditions. 



Section 5.3: Signal propagation in TR lines to and from interface

What happens when a signal encounters the interface between two transmission lines and a reflected signal is created and the transmitted signal is changed?



Section 5.7: Reflections from open and short w/ resulting dynamic voltage video on TR line

This video explains what happens to a signal when it encounters different impedances at the end of a transmission line. If you do not understand reflections, the behavior of the currents is very confusing. But I show you the inner workings of the current so it becomes obvious.



Section 5.8: TR Line analysis and steady-state simple source and load analysis

This video resolves the paradox. Why do we see a 2 v signal at the end of a transmission line if we only sent a 1 V signal into the line?
