1. A fluctuating oscillator comprising:
a processor including a digital circuit,
wherein the processor includes
a random variable generation unit that generates a random variable,
a lookup table that stores a waveform signal in advance,
a computation unit that imparts fluctuation to the waveform signal based on the waveform signal read from the lookup table, the random variable generated by the random variable generation unit, and a pulse signal to be fed back,
a threshold discrimination unit that generates a pulse signal by comparing a fluctuating signal output from the computation unit with a predetermined threshold, and
a feedback loop that causes the pulse signal to be fed back to the computation unit.
