EMC Design Classic Q & A I

1Q. Why do EMC design for products?

A: In order to meet the functional requirements of the product, reduce debugging time, and meet the requirements of EMC standards, so that the product will not produce electromagnetic interference to other equipment in the system.

2Q. What are the aspects of EMC design for products?

A: circuit design (including device selection), software design, circuit board design, shielding structure, signal / power line filter, circuit grounding design.

3Q. For EMC, why it is always described in decibels (dB) units?

A: Because the range of amplitude and frequency to be described is very wide, it is easier to represent logarithmic coordinates in graphics, and dB is the unit when represented by logarithm.
