N+1 BIT RESOLUTION, FROM AN N BIT A/D CONVERTER In microprocessor based control systems wherein several analog sensors are used to generate control signals of N bits, the system herein generates a digital signal having an N+1 bit resolution of the information. The N+1 bit resolution is generated from an N bit A/D converter by means of a network changing the reference voltage input to the A/D converter by an offset voltage which is a function of the least significant bit position. The network in, the absence of a control signal, generates a first range of reference voltages and in the presence of the control signal generates a second range wherein the limit voltages are change by the offset …
