Abstract: PURPOSE:To improve S/N and assure compatibility with the conventional format by controlling a function of a noise canceller interlockingly with a change over of the quantity of the first and the second deemphasis. CONSTITUTION:When a control signal SC of high level is supplied to a terminal 25, the quantity of a preemphasis of a preemphasis circuit 4 is changed over to the second quantity of the preemphasis and the quantity of a deemphasis of a deemphasis circuit 16 is changed over to the second quantity of the deemphasis, respectively. At this time, connecting switches 86, 95 of a comb line filter 18 and a noise canceller 19 are turned on, and their functions are scarcely executed. Accordingly, by enlarging the quantity of the preemphasis, the S/N is improved. When the control signal SC of low level is supplied to the terminal 25, it is changed over to the first preemphasis and the first deemphasis, respectively and the connecting switches 86, 95 and turned off. Thereby, the compatibility of the conventional device can be assured.
