Abstract

PURPOSE:To detect even drop-out of a comparatively high frequency component, existing in a reproducing FM signal of a video disk, by using plural detecting levels. CONSTITUTION:An output (b) of a band pass amplifier is distributed to 3 detecting circuits. In the first circuit (1, 2, 3 and 4), such processing as shown by waveforms (c), (d) and (e) is executed, and drop-out D, E and F are detected as shown by a waveform (f) by a detecting level (A). In the second circuit (6, 8), such processing as shown by a waveform (g) is executed, and drop-out H is detected as shown by a waveform (i) by a detecting level (B). In the third circuit (7), such processing as shown by a waveform (b) is executed, and drop-out G is detected as shown by a waveform (h) by the detecting level (B).
