Abstract

PURPOSE:To improve the reliability of a signal detecting circuit by signal- detecting only a true waveform peak of an analog reproducing signal being an information point, and eliminating completely a pseudo pulse. CONSTITUTION:In the vicinity of a true waveform peak of an analog reproducing signal being an information point, a pulse of prescribed width is generated by a clamping circuit 5, a level detecting circuit 6 and a pulse generating circuit 7. Subsequently, AND by an AND gate 8, of this pulse and a peak detecting pulse from a peak detecting circuit 4 is outputted as an information detecting signal. Accordingly, in the AND gate 8, a pseudo pulse by a noise which is contained in the analog reproducing signal is eliminated completely, and it does not occur to signal-detect the pseudo pulse as an information point by mistake. In such a way, the reliability of a signal detecting circuit can be improved.
