![]() In the early days of electronics systems, pops, bangs and general noise received by radios were taken as being part of "experience" of listening to a radio - even if they were man-made from other local electrical equipment. These any many more examples may EMC a crucial element of any electronics design. Others may utilise digital electronics systems that could be falsely triggered by transient signals. Some of these transmit signals, while many others are sensitive receivers. However today the number of electronics items in everyday has vastly risen. In the early days of electronics comparatively few items of electronics equipment were in use. Often when dealing with EMC it is necessary to ask: what is EMC and to have a definition.ĮMC definition: EMC is defined as the ability of devices and systems to operate in their electromagnetic environment without impairing their functions and without faults and vice versa.Įlectromagnetic compatibility, EMC ensures that operation does not influence the electromagnetic environment to the extent that the functions of other devices and systems are adversely affected. Defining what EMC is and understanding the concepts enable electromagnetic compatibility to be achieved from the outset.ĮMC basics EMI interference basics EMC standards CISPR11 CISPR16 CISPR22 FCC 47 part 15 EMC design techniques EMC compliance testĮlectromagnetic compatibility, EMC is the concept of enabling different electronics devices to operate without mutual interference - Electromagnetic Interference, EMI - when they are operated in close proximity to each other.Īll electronics circuits have the possibility of radiating of picking up unwanted electrical interference which can compromise the operation of one or other of the circuits. What is EMC: Electromagnetic Compatibility Basics EMC is of increasing importance as the number of wirelessly connected devices increase. ![]()
