This is the first in a series of EMC videos on PCB design for EMC.  This series is specifically intended to cover mixed signal designs where the digital signals are less than 100 MHz and clock rise times are greater than 1 ns. This introductory video will cover some of the basic definitions and equations related to EMC design. The video series will also provide measured test results to support the EMC theory. This video will cover the types of experiments, test tools and test methods used throughout the series.
