Camera control systems, stabilized mounts, navigational computers and related photo-optical control systems can produce high levels of electro-magnetic interference from pulse circuits, switches and relays. In military applications such interference must be controlled carefully. This paper considers the problem in terms of current military specifications for measurement and acceptable limits. It covers methods of noise suppression and describes the development of a postage-stamp size resistance capacitance filter for high attenuation of conducted and radiated interference.
