Laboratory simulation of multiple sources of motor vehicle radio interference

Back in the 1930s some engineers recognized that RFI (radio frequency interference) could be a nuisance. After years, with advancing technology, it turned into an even greater problem especially with the advent of high-tech communications systems and microprocessor-based control systems. Recognition of the problem led many engineers to become involved in EMC (electromagnetic compatibility) and as a result several test standards, including some for automotive EMC testing, have been made.
