Electromagnetic Compatibility (EMC) Part 3 - Signal Transmission and Grounding
In this class we dive into the details of signal transmission lines and grounding including types of signal coupling and reflections on transmission lines and the effects on PCB traces. (November 2023)
In this course, we dive into the details of signal transmission lines and grounding. We will demonstrate that the ground forms an integral part of the signal pathway. We will then explore the problems of coupling through common impedances or shared ground impedances. Furthermore, we will examine the effects of printed circuit board (PCB) layout and provide a comprehensive analysis of transmission lines and the reflections that occur within them. We will also investigate the implications of having single traces on the PCB in close proximity to each other and discuss the mutual coupling between these individual traces.
