Abstract: PURPOSE:To prevent the deterioration in the sharpness of the beam at high region, by easily forming the video output signal and the scanning speed modulation signal, through obtaining differentiating signals of the first and second order at the leading and trailing of an original video signal.

Abstract: PURPOSE:To avoid the definition deterioration by increasing the output load resistance at the output stage of each primary color signal, decreasing the power consumption at each output stage, detecting the rise/fall part of the luminance signal to send it to CRT, and modulating the scanning velocity of the electronic beam.
