Return Paths | Mixed Signal PCB Design: Part One

One of the fundamental aspects of any circuit diagram is the return current path. In a circuit diagram and a schematic diagram, the path that electric current follows to return to the low potential side of a power source should be obvious, but it may not be so obvious in a PCB. 0:00 Intro 1:16 How Signals Travel on Traces 2:30 What Is a Displacement Current? 3:45 Examining Signal Return Paths 4:51 Analogue Vs.
