design book, is now available at the course Moodle site.
If you are interested in using toroidal inductors for Mini-Project #1,
you should consider reviewing the sections near the end of the reading.

Optional Reading (2/24/2025)
The following supplemental readings are now available at the Moodle site
in the "Additional Resources" section.
- "Alternative Formula for Calculating the Forward Voltage Coefficient" -
This is a set of ECEG 390 lecture notes that describe a
potentially more useful formula for calculating the coefficient
V0+ used in the expression for the total
voltage along a transmission line than the one given in most textbooks.
The notes show that the formula simplifies greatly when the source
impedance equals the characteristic impedance of the line.
- "Calculating Power Wave S-Parameters Using Only Port Voltages or
Currents" - This is a paper that I presented at a conference two years
ago that summarizes how a more general form of S-parameters can
be calculated from the port voltages or currents of a network.
Neither document is required reading for the course. The first one is
offered in case you would like to review background material.
The second one goes beyond the material in the course notes "Matrix
Representations of Networks: Z, Y, and S-Parameters" and is offered in case
your are interested in advanced applications.
