DEVICE FOR CONVERTING ANALOG-DIGITAL AND CONVERTING METHOD THEREOF

摘要

PURPOSE: A device for converting an analog-digital and a converting method thereof are provided to reduce a converting time required for converting an analog signal to a digital signal to one cycle for converting efficiently in a short time. CONSTITUTION: A device for converting an analog-digital comprises: a storing instrument storing a digital standard signal; a digital-analog converting instrument(71) converting the digital standard signal to an analog signal for outputting an analog standard signal; and a comparing instrument comparing the analog standard signal inputted from the digital-analog converting instrument with an input analog signal inputted for converting for outputting the result of comparison.
