Abstract
An information processing device has a digital-to-pulse converter which outputs a pulse signal including a pulse having a pulse length in accordance with a digital input signal, and a selective oscillator which performs an oscillation operation while the pulse of the pulse signal is output and holds an oscillation operation state at a point of time where the output of the pulse is stopped.
