<p>PURPOSE:To accurately display a tracking dislocation by automatically switching a switching means for switching and displaying a level before and after a demodulation when a reproducing output before the demodulation goes below a prescribed level. CONSTITUTION:The level of a reproducing output before the demodulation by an FM sound output reproducing output rectifier circuit 10 or the like and a reproducing output level after the demodulation by a demodulating circuit 7, a sound signal rectifier circuit 12 or the like are switched through a display switching circuit 11 and selectively displayed on a level display part 13. When the reproducing output level before the demodulation goes below the prescribed level, the circuit 11 is automatically switched by the comparison output of a comparator 16 and the reproducing output level before the demodulation is displayed on the display part 13 and a tracking dislocation can be accurately displayed.</p> |
