Controlling Conducted and Radiated EMI by Design (DS20-2-0)

SynopsisMost design engineers are competent in designing electronic products to perform specific features and functions. However, they lack the necessary background to design the products to meet international EMI specifications. Although some quick "hard-fixes" to a product at the final design stage may help it to comply with the required EMI specifications, these under-the-pressure remedies can very costly to implement. On the other hand, increasing cost competitiveness in the electronic market has forced manufacturers worldwide to look into cost-effective EMI solutions.

Course Highlight
You will learn concise, practical treatments of how EMI is generated by an electronic product, and how to suppress it through proper design at the initial product development stage, without incurring unnecessary additional costs.
