APPARATUS FOR INPUT TIME MEASUREMENT OF INPUT SIGNAL

摘要

The present invention relates to a device which measures time when a signal is inputted. More specifically, the present invention provides a device for measuring signal input time which measures time when a signal is inputted more precisely than a reference clock by using a delay circuit. The device for measuring signal input time comprises: a signal input unit (100); a clock generating unit (200) which generates a reference clock; a delay unit (300) having at least one delay circuit (310); a detection unit (400) which detects a signal inputted from the signal input unit (100); and a calculation unit (500) which calculates input time of the signal inputted from the signal input unit (100) based on data detected by the detection unit (400).
