Title: Circuit arrangement for the digital control of operating functions via sensor electrodes, especially in radio and television receivers

Abstract: The invention provides for the digital control of the operating functions in a radio or T.V. receiver using sensor electrodes in place of mechanical control devices. A sensor control panel is provided for directly setting an electronic stepping circuit to a desired condition. The electronic stepping circuit is particularly adaptable for receiving sequential remote control signals and thereby greatly reduces the cost of adapting a receiver for remote control operation.
