Claim 1
Independent Claim
148 words
THE METHOD FOR CONVERTING AN ANALOG VOLTAGE INPUT TO A DIGITAL PULSE COUNT INDICATIVE OF THE MAGNITUDE OF THE ANALOG VOLTAGE, WHICH CONSIST IN CONVERTING THE INPUT ANALOG VOLTAGE INTO POSITIVE REPRESENTATIONS AND NEGATIVE REPRESENTATIONS OF THE ANALOG VOLTAGE, PRODUCING A TIMED SIGNAL OF PREDETERMINED DURATION, PRODUCING A LINEAR SAWTOOTH VOLTAGE STARTING AT THE BEGINNING OF EACH TIMED SIGNAL AND DIMINISHING LINEARLY IN AMPLITUDE AT A PREDETERMINED RATE, PRODUCING A SERIES OF RECURRING DIGITAL COUNT PULSES, COMPARING THE POSITIVE REPRESENTATIONS WITH THE SAWTOOTH VOLTAGE TO PRODUCE A FIRST TRIGGER PULSE WHEN THE SAWTOOTH VOLTAGE REACHES A CRITICAL LEVEL, COMPARING THE NEGATIVE REPRESENTATIONS WITH THE SAWTOOTH VOLTAGE TO PRODUCE A SECOND TRIGGER PULSE WHEN THE SAWTOOTH VOLTAGE REACHES ANOTHER CRITICAL LEVEL, AND COUNTING THE NUMBER OF RECURRING COUNT PULSES PRODUCED IN THE TIME INTERVAL BETWEEN THE TRIGGER PULSES AS A DIGITAL REPRESENTATION OF THE MAGNITUDE OF THE ANALOG VOLTAGE.
