Abstract

PURPOSE:To improve an accuracy by converting a signal reproduced by means of a reproducing means to a digital signal and, thereafter, correcting the non- linearity of the reproducing means. CONSTITUTION:After a demodulated signal is A/C-converted, when a distortion is corrected by a table conversion in utilizing a linearity correction ROM 411, etc., having a table corresponding to a converting characteristic, an arbitrary correction can be executed. A corrected signal is encoded, by a digital processing circuit 405, in being matched with an NTSC system in the form of the digital signal, and the signal is converted to an analog signal. In such a way, without increasing adjustment items, after a demodulating wave with a high performance is stably obtained by a circuit to be conventionally used, the A/D conversion is executed, and thereafter, a linearity is corrected. Thus, adjustment points can be decreased, and the accuracy can be improved.
