All consumer electronic devices need to meet EMC standards. By including EMC compliant design at an early stage, additional costly iterations can be avoided later on down the line. In this eSeminar we will present how board-level EMC design can significantly reduce emissions at their source. We will then focus on system level EMC, discussing different approaches of segmenting the system for an efficient simulation workflow. Finally we will analyze immunity, by demonstrating how different return current path configurations can affect performance of the device due to cable entry susceptibility.
