Reflection rf
WebWhen a reflection occurs, the voltage and current at the input to the load component on a transmission line may exhibit overshoot or undershoot, depending on the polarity of the reflected signal compared to the incoming input signal. The main equation that defines the strength of a reflected signal is the reflection coefficient equation.
