The need for an organized approach to EMI (electromagnetic interference) control

EMI control refers to the ever-increasing problem of controlling the adverse effects of electromagnetic interference (EMI) on electronic equipment. Atmospheric noise, due to the phenomena of solar radiation and the ionosphere, is one form of ambient interference, but man-made noise adds to the ambient solar interference and increases the ambient intensity by many orders of magnitude. Descriptions are given of several undesirable effects of man-made interference. The interference problem is discussed, as well as many reasons for concern. An approach to EMI control is suggested, including the outline of a proven EMI control program.
