Impedance Mismatch as the Root Cause of Reflection in Transmission Line
In high-speed PCB design, impedance mismatch is the root cause of reflection in transmission line systems, degrading signal integrity. When a signal encounters a change in characteristic impedance, part of its energy reflects back, causing overshoot, undershoot, and logic errors. This article explores the physics, mathematics, and practical solutions to eliminate reflections. The Physics of…
