Zusammenfassung:	The utility model discloses a VGA and chroma component interface signal front-end processing compensation circuit. The compensation circuit comprises a bias signal logic circuit, a bias circuit, an anti-aliasing the filter circuit, a single-ended to differential circuit, an analog-to-digital converter and an averaging circuit. One input end of the bias signal logic circuit receives a bias signal, and the output end is connected with the bias circuit. The input end of the bias circuit is connected with the bias signal logic circuit, and the output end is connected with the anti-aliasing filter circuit. The input end of the anti-aliasing filter circuit is connected with the bias circuit, and the output end is connected with the single-ended to differential circuit. The input end of the single-ended to differential circuit is connected with the anti-aliasing filter circuit, and the output end is connected with the analog-to-digital converter. The input end of the analog-to-digital converter is connected with the
