Abstract
Unintentional emissions are controlled responsive to the spectral content of the display signal. A video display apparatus comprises a cathode ray tube for video image display. A processor controls a magnitude of a video image display signal coupled to the cathode ray tube for display in response to an emission control signal. A generating means is coupled to the processor for generating the emission control signal responsive to a component of the video image display signal.
