ABSTRACT:
The accuracy of the conversion of an analog signal to digital form is improved by amplifying the input signal by different factors and automatically utilizing the highest amplified input signal which has a voltage level within operational limitations in the analog to digital conversion process. Output data from a digital computer, based on the input data, is converted from digital form to analog form and is routed to a required location by the use of control logic and optically isolated digital signals used to address other computers.
