EMC Design Techniques

Good EMC design techniques are not too difficult to implement if they are introduced at the earliest stages of design. If modifications need to be made later in the design to meet EMC requirements, then it becomes much harder.EMC design from the earliest stages of the project follows some straightforward and common sense design approaches.
