Abstract
PURPOSE: To automatically equalize the waveform distortion of the video signal caused in the transmission system, by controlling the transversal filters through the monitor of a part of the waveform distortion of the second power sinusoidal wave pulse of the test signal superimposed during the vertical balnking period.
CONSTITUTION: In synchronizing with the second power sinusoidal waveform of the test signal superimposed during the vertical blanking period of color television signal, the sampling pulse corresponding to the time before the 2T bar rising and after the trailing is generated. Further, the reception 2T pulse of the output of the reference voltage generating means 9 and that of the transversal filter output are compared 16 at the sampling time, to produce the error code. This error code produces 18 the control information, which sequentially changes little by little the coefficient of the adjusted taps 4 to 7 of the transversal filters toward the correction of the waveform distortion.
