Analog signal input periodic and non-periodic selection analog-to-digital converter

摘要

The analog-to-digital (A/D) converter includes a channel selector (2) for selecting a number of analog signal inputs (11-1n) an A-D converter (5). A control device (3) controls the channel selector (2) either to work in a sampling work mode at the time of receiving a start control pulse for sampled conversion, or at the time of receiving a start control pulse, for discrete conversion, to work in a discrete work mode with reference to the remainder.
