Impedance Discontinuity and Signal Reflection in PCB Transmission Lines

We previously quickly discussed signal reflection in our PCB Transmission Line series. This is an in-depth article about this very important topic that PCB designers should master. The first thing to remember is that reflections in transmission lines occur due to impedance discontinuity.

How to Analyze a PCB Transmission Line?

After establishing what a PCB transmission line is and talking about signal speed and propagation delay, and the critical length, the controlled impedance, and the rise/fall time of a PCB transmission line, we discussed impedance discontinuity and signal reflection. Today, we are going to explain how to analyze a PCB transmission line using quantities, such as voltages and currents, and line parameters, such as resistance, inductance, capacitance, and conductance.
