What does EMC stand for? The Acronym Finder defines it as "magnetic compatibility."
There is a concept of enabling different electronics devices to operate without mutual interference.All electronics circuits have the chance of picking up unwanted electrical interference which can compromise the operation of one or other of the circuits.It is important to have a definition of what is EMC when dealing with it.It is defined as the ability of devices and systems to operate in their environment without impairing their functions and without fault.The functions of other devices and systems are adversely affected if operation does not influence the environment.In the early days of electronics, few items of equipment were used.The number of electronics items is increasing.Some transmit signals while others are sensitive.Digital electronics systems may be used by others.A crucial element of any electronics design can be seen in these examples.In the early days of electronics systems, pops, bangs and general noise received by radios were taken as being part of the experience of listening to a radio, even if they were made from other local electrical equipment.Military applications had the first concerns of the effects of electrical interference on electronics systems.The electronic pulse generated by an explosion and its effect on equipment became a concern after the Second World War.The effects of high powered radar systems on equipment were a concern.The risks to electronics equipment became visible later.The electronics equipment was damaged and they could also set falsetriggers.The use of logic circuitry grew rapidly in the 1970s.If these items were to work well in the real world, there would be need for precautions to be incorporated into the design.Many nations became aware of the problem as a result of this growing realization.Directives were issued to the manufacturers of electronic equipment, defining standards that the equipment should meet before it could be sold.The European Community was the first place where the requirements were enforced.Most types of equipment have been able to operate without interference thanks to the introduction of EMC standards.This has been particularly important with the rapid growth in the use of mobile phones.The interference that causes impaired performance is known as Electromagnetic interference.It is important that items of electrical equipment are compatible and can operate in the presence of each other.The generation of unwanted energy is referred to as the EMI emissions.These need to be reduced to make sure they don't disrupt other equipment.The susceptibility of an item of electronics is how it reacts to interference.The design of the circuit is to ensure a high level of immunity.There is a name for the unwanted radiation that can cause interference to other items of electronics equipment.There are many ways in which interference can be carried from one piece of equipment to another.The effects of the interference are mitigated by understanding these methods.Continuous interference is a type of interference that is maintained in the form of a radio signal.It could be a wideband noise from an unscreened oscillator.This form of interference consists of a short impulse.It could be from a circuit being switched or from an electrical discharge.It is important to know how the interference is travelling from the transmitting device to the receiving device.Many of the paths are hard to define.Many problems are alleviated by good initial design.Many standards have been introduced to help manufacturers meet the levels they need to maintain full electromagnetic compatibility.Taxis driving past a house while using their radio telephone were more likely to disrupt the operation of a television than a few years ago.To ensure the required levels of compatibility were attained, it became necessary to introduce EMC standards.Any electronics design project now includes EMC.With standards now in place and enforced across the world, any new product needs to be tested to make sure it complies with the relevant standards.While this presents an additional challenge to the electronics design engineer, it is essential that good EMC practices have been employed and that the product's performance is sufficient to ensure it operates correctly under all reasonable scenarios.Circuit symbols return to the circuit design menu...
When electronic devices are operated in close proximity to each other, they can operate without interference.
All electronics circuits have the chance of picking up unwanted electrical interference which can compromise the operation of one or other of the circuits.
It is defined as the ability of devices and systems to operate in their environment without impairing their functions and without fault.
The functions of other devices and systems are adversely affected if operation does not influence the environment.
