DELAY APPARATUS, POWER SUPPLY APPARATUS, AND SIGNAL DELAYING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a delay apparatus with high resolution without increasing the circuit scale.

SOLUTION: The delay apparatus (delay circuit 10) for inputting a signal with periodicity and outputting the signal with a delay by a prescribed time T0is provided with: a sampling circuit (A/D converter 11) for sampling the signal at a prescribed period TS; a storage circuit (RAM 14) for storing data sampled within a prescribed time in the past by the sampling circuit; and an estimate circuit (DSP 12) for estimating the value of a signal before the prescribed time T0from a certain point of time and at a point of time between samplings from the data stored in the storage circuit.
