Abstract
PURPOSE: To enhance the precision of conversion and make it possible to facilitate set and change of a blind sector, by comparing a digital signal, which is obtained by subjecting an analogue input signal to A/D conversion, with a reference signal and outputting the digital signal.
CONSTITUTION: The analogue input of line 1a is inputted to A/D converter 4 after amplified by 1 and is converted to a digital signal according to the control signal of line 8a, and the digital signal is further inputted to comparator 5 through line 4a. Then, comparator 5 compares the digital signal of line 4a and the reference signal of line 6a with each other and converts the signal of line 5a to "1" for the digital signal larger than the reference signal and converts the signal of line 5a to "0" if the reference signal is larger than the digital signal and difference between these signals is larger than the signal of line 7a. In this case, if difference between signals above does not exceed the magnitude of the signal of line 7a determining a blind sector though the reference signal is larger than the digital signal, the preceding value is held and is supplied to the external. As a result, the precision of conversion can be enhanced, and set and change of the blind sector can be facilitated.
