Analog-to-digital converter with programmed characterizing function
Abstract
Abstract THE INVENTION CONTEMPLATES A METHOD AND APPARATUS FOR ACHIEVING A DIGITALIZED AND QUANTIZED ROOT FUNCTION OF AN INPUT ANALOG VOLTAGE, WITH TECHNIQUES THAT INVOLVE NO DEPENDENCE ON ANALOG COMPONENTS FOR THE ROOT-TAKING FUNCTION. THE BASIC ACCURACY OF THE INVENTION DEPENDS UPON CLOCK-TIMING OF A COMPUTER, THE CHARACTERIZING FUNCTION OF WHICH IS RELATED TO TIME AND APPEARS ACROSS AN OUTPUT-SUMMING NETWORK. THIS OUTPUT VOLTAGE, IN COMPARISON WITH THE GIVEN INPUT ANALOG VOLTAGE, IS UTILIZED TO OPERATE A GATE, IN SUCH MANNER THAT THE NUMBER OF GATED CLOCK PULSES IS THE QUANTIZED ROOT FUNCTION OF THE INPUT ANALOG VOLTAGE. THE PROCESS MAY BE AUTOMATICALLY RECYCLED TO PRESENT CURRENT DISPLAY OR AVAILABILITY OF THE CIRCUIT''S OPERATION ON THE INSTANTANEOUS MAGNITUDE OF THE INPUT ANALOG VOLTAGE.
