Abstract

PURPOSE: To obtain four functions and characteristics only by one 1H delay device by giving a coefficient corresponding to the transfer function of the characteristics at the time of the operational characteristics in which a vertical direction de-emphasis and a line noise cancellor operation are used in common.
CONSTITUTION: A titled circuit is constituted in such a way that it has the coefficient of Kp=1 and X=X1 at the time of the vertical direction emphasis, the coefficient which is Kp=0, or a third switch 13 is turned off, and X=X2 at the time of the noise cancellor operation, and the coefficient that X=-m/(1+m) and Kp=-X corresponding to the transfer function 1/(1+m)-mz-1((m) signifies the coefficient and z-1 means the 1H delay device)of the characteristics at the time of the operation characteristics in which the vertical direction de-emphasis and the line noise cancellor operation are used in common. With only one 1H delay device 11, four functions of the characteristics in which the vertical direction emphasis, the noise cancellor, the vertical direction de-emphasis are added, and a drop-out compensation are attained.
