Abstract
A signal detecting device detects, as analog voltage signals, a current flowing through an exciting coil of an electric power generator, a source voltage and a temperature of a regulator that change as a current is fed to the exciting coil by an FET. These analog voltage signals are subjected to A/D conversion by a single A/D converter circuit. The detected current is subjected to A/D conversion in a period during which the FET is ON, while the detected source voltage and the detected temperature are subjected to A/D conversion in a period during which the FET is OFF.
