Abstract

PURPOSE:To obtain an analog input device for deriving plural analog inputs as those which have been obtained at the same time, by sample-holding plural analog input signals in one sample-holding circuit, and reproducing those data. CONSTITUTION:An analog signal 5 consisting of n+1 points is selected in order in accordance with a counter 7, is amplified, and after that, is inputted to a sample- holding circuit 9 and an A/D converter 10. This output (di), a value (di') related to an input point in a register 11 in which a digital value of 1 period sampling before is recorded, a time DELTAt for converting the analog signal to a digital signal by the A/D converter 10, a counter value (i), and a digital value Di in a reference time by a sampling period T are operated and outputted by Di=di'+(di-di')i.DELTAt/T.
