Abstract
A delay device with high resolution is provided without increasing circuit size. In the delay device which is inputted a signal with periodicity and outputs the signal after a delay by a prescribed time, there are provided a sampling circuit for sampling the signals at intervals of a prescribed time period, a storage circuit for storing data sampled by the sampling circuit in a past certain amount of time, and an estimation circuit for estimating the value of the signal at a time that is a prescribed time period before a certain time point and between the samplings based on the data stored in the storage circuit.

A delay device which is inputted a signal with periodicity and outputs the signal after a delay by a prescribed time T0, comprising:
- a sampling circuit for sampling the signals with periodicity at intervals of a prescribed time period Ts;
- a storage circuit for storing data sampled by said sampling circuit in a past certain amount of time;
- and
- an estimation circuit for estimating a value of a signal at a time that is the prescribed time T0 before a certain time point and between the samplings based on the data stored in said storage circuit.
A power supply device having a delay device which is inputted a detection signal of voltage or current of a commercial power source and outputs the signal after a delay by a prescribed period of time T0 being a time period of the voltage or electric current of the commercial power source or its integral multiple, comprising:
- a sampling circuit for sampling the detection signals of the voltage or current of the commercial power source at intervals Ts which is shorter than the prescribed period of time T0 being a time period of the voltage or current of commertial electric source or integral multiple of the time period,
- a storage circuit for storing the data sampled by said sampling circuit in a past certain amount of time,
- an estimation circuit for estimating a value of a detection signal at one point being the prescribed time T0 before a certain time point and between the samplings based on the data stored in said storage circuit, and
- a control circuit for controlling an internal circuit of said power supply device based on the value obtained by said estimation circuit.
A computer-readable program product for delaying signals, which makes a computer execute a processing of inputting a signal with periodicity and outputting the signal after a delay by a prescribed time T0, makes the computer function as a sampling means for sampling the signals with periodicity at intervals of a prescribed time period Ts, a storage means for storing the data sampled by the sampling means in a past certain amount of time, an estimate means for estimating a value of the signal at a time that is the prescribed time T0 before a certain time point and between the samplings based on the data stored in the storage means.
