Coupled RLC circuits are solved as coupled harmonic oscillators. The detuning of the circuits is calculated.

The classic problem of the resistance cube is solved. In addition, variations are outlined such as the C- and RLC-Cube

The serial RLC circuit is solved for dissipation and eigenfrequencies.

Fabry-Perot resonances are derived for transmission lines. This basic model can be applied to a wide range of physical phenomena.

In this problem we will learn about basic principles such as the reflection of signals and impedance matching for transmission lines.

In this problem we will derive the telegrapher equation needed to understand communication devices.
