I’m sure that some folks who have stumbled on this web site are confused.  There’s a company called EMC and they’re wondering what this site has to do with them?  The answer is – nothing.

EMC stands for Electromagnetic Compatibility.  EMC is defined in MIL-STD-463A (in 1977) as “The condition which prevails when telecommunications (communication-electronic) equipment is collectively performing its individual defined functions in a common electromagnetic environment without causing or suffering unacceptable degradation due to electromagnetic interference to or from other equipments/systems in the same environment.”  In other words, it means that your product is not generating excessive RF noise and is ignoring electromagnetic signals which might otherwise interfere with its proper operation.

I hope you find the information on this web site useful.  If you have questions, or need additional help on EMC matters, please contact me.
