Computer EMI

The case of computer EMI is very serious. Just place an AM radio anywhere close to a modern computer and you will hear lots of hash. In fact, with computer clock speeds reaching several hundred megahertz, the interference to FM radios can be tremendous. Figure 15-13 shows a method for connecting a digital connector pin that can cany EMI to a printed wiring board.

Because the filtering is bidirectional, it will attenuate the noise going out as well as that coming into the computer.
