ABSTRACT:
An oscillation detecting apparatus for detecting oscillation of a signal includes a high pass filter for generating an alternating current signal from which a direct current component of the signal is removed, a slicing circuit for generating a limit signal which results from restricting an amplitude level of the alternating current signal to a level lower than a predetermined level, an integration circuit for integrating a waveform of the limit signal during a predetermined period, and a comparator for detecting whether or not the signal oscillates based on a value of the waveform integrated by the integration circuit.
