Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) are critical concerns in electronic design. EMI refers to the unwanted interference caused by electromagnetic radiation, while EMC refers to the ability of electronic devices and systems to function properly in the presence of electromagnetic interference.
EMI and EMC are important considerations in electronic design because electronic devices and systems are increasingly being used in environments where they are exposed to a wide range of electromagnetic interference. This in to ensure correct functionality in the presence of other devices that may emit EMI.
That’s one of the reasons why it’s important to understand the environmental factors involved when looking at electronic design projects.
Proper EMI and EMC Design
Proper EMI/EMC design is crucial to ensuring that electronic devices and systems function properly in these environments. This includes designing devices and systems to minimize the amount of electromagnetic radiation they emit, as well as designing them to be resistant to interference from external sources.
One way to achieve this is by using shielding and filtering techniques to reduce the amount of electromagnetic radiation emitted by devices and systems. This can be done by using metal shielding around sensitive components, or by using filters to reduce the amount of electromagnetic energy that enters or exits a device or system particularly through all connected cabling.
Types of potential interference
It is also important to consider the different types of environment that a device or system may be exposed to and design the system accordingly. For example, a device or system that will be used in a hospital may need to be designed to meet different EMI/EMC requirements than a device or system that will be used in a factory.
Proving Compatability
It is important to perform testing on electronic devices and systems to ensure that they meet the necessary EMI/EMC standards. This can be done by using specialized test equipment and procedures to measure the electromagnetic emissions and susceptibility of devices and systems.
DSL have access to testing facilities to allow us to replicate a variety of different environments. This testing is vital to ensure that any devices work properly.
EMI/EMC design is an essential aspect of electronic design. It is important to design electronic devices and systems that are resistant to electromagnetic interference, while minimizing the amount of electromagnetic radiation they emit.
