Abstract
In the clamping circuit, errors in direct current components contained in R, G and B signals from a matrix circuit are detected by comparing circuits and these errors are fed back to respective input capacitors through a reverse matrix circuit. The respective input capacitors are charged and discharged in response to the errors from the matrix circuit and the direct current parts of the outputs of the matrix circuit coincide so that the clamping levels of the outputs of the matrix circuit may coincide.
