Abstract
A video clamping correction circuit for connection with a video clamping circuit for removing an energy dispersal signal in a receiver in an energy dispersal satellite communication system, comprises: a clamping circuit including a clamping capacitor and a clamping diode for producing a video output signal; and a correction circuit including a detecting resistor for detecting a clamping current flowing through the clamping diode, a first amplifier for inverting and amplifying a signal developed across the detecting resistor in proportion with the clamping current, an integrating circuit connected to an output of the first amplifier for integrating an output signal from the first amplifier, an integration correcting circuit connected to the integrating circuit for processing an integrated waveform of the output signal into approximation with a distorted waveform in the video output signal from the clamping circuit, and a circuit for adding an output signal from the integrating circuit and integration correcting circuit to the video output signal from the clamping circuit for cancelling out the distorted waveform in the video output.
