PURPOSE:To simplify the constitution and to make the display of a curve of both channels clear by adopting full lighting of display dots as to one of two channels and flickering as to the other so as to display each correction curve. CONSTITUTION:The frequency correction curve of right and left channels is displayed on a common display panel 1 having dot display of XY matrix form. The curve of the left channel is indicated by a display dot 2L lighted fully and the curve of the right channel is displayed by a blinked display dot 2R. Even when the dot matrix display is used in common use for the right and left channels, both the correction curves are identified very clearly visually. Thus, the constitution of the display panel and the drive circuit are simplified to attain the correction curve display with high quality. |
