| Zusammenfassung: | PURPOSE:To improve the clamp method of the bottom clamp system chroma integrated circuit of a color television. CONSTITUTION:The video input signal of a bottom clamp system chroma integrated circuit 104 is impressed after a DC interruption is operated, and the synchronizing signal part of the video input signal is omitted, so that the potential of a pedestal potential part can be controlled to be constant. Thus, the effect of a bottom clamp 103 can be reduced, and the effect equivalent to the chroma integrated circuit of a pedestal clamp can be obtained. |
