WebExpressions for incident and reflected current waves can be similarly written. If Z c is pure resistance, current waves can be simply obtained from voltage waves by dividing by Z c. If the load impedance i.e. the line is terminated in its characteristic impedance, the reflected voltage wave is zero (V R – Z c I R = 0). Web23. jún 2024 · The voltage represented by your graph is the superposition (sum) of two AC signals, one propagating in the forward direction along the transmission line, and one propagating back. We can represent an AC signal of a given frequency as a vector that represents its amplitude and phase.
