Electromagnetic compatibility (EMC) is the ability of electronic equipment to function properly without interference from noise sources and without causing disturbances to other electronic equipment. This article will help the reader understand the modes of electrical noise propagation, how fields interact, and the methods of testing for EMC, helping to provide the basis for designing low-emissions, low-susceptibility electronic equipment.
This article describes a laboratory experiment that shows the impact of the decoupling capacitors and a PCB trace length on the signal integrity in a CMOS inverter circuit.
