Course Objectives
- The course provides basic information on the different electromagnetic Interference problems occurring in intersystem and their possible mitigation techniques in Electronic design.
- The course objective is to understand EMI sources, EMI problems and their solutions at PCB level.
- The course objective is also to understand sub system level design and to measure the emission, immunity level from different systems to couple with the prescribed EMC standards.
