A VOLTAGE MEASURING AND CONVERSION SYSTEM FOR MEASURING AN UNKNOWN ANALOG VOLTAGE COMPRISING CONTROL MEANS CONNECTED TO INITIATE THE OPERATION OF SAID MEASURING AND CONVERSION SYSTEM, VOLTAGE GENERATING MEANS FOR GENERATING A SUBSTANTIALLY LINEARLY INCREASING REFERENCE VOLTAGE, CONNECTED TO SAID CONTROL MEANS, A COUNTING SYSTEM, MEANS FOR PROVIDING CONSTANT FREQUENCY SIGNALS TO SAID COUNTING SYSTEM, AND COMPARATOR MEANS CONNECTED TO CONTROL THE FLOW OF CONSTANT FREQUENCY SIGNALS TO SAID COUNTING SYSTEM, SAID COMPARATOR MEANS INCLUDING FIRST COMPARISON MEANS CONNECTED TO RECEIVE SAID REFERENCE VOLTAGE AND INCLUDING MEANS TO PROVIDE A START PULSE TO INITIATE THE FLOW OF CONSTANT FREQUENCY SIGNALS AT A FIRST PREDETERMINED TIME AFTER THE INITIATION OF SAID REFERENCE VOLTAGE, AND SECOND COMPARISON MEANS CONNECTED TO RECEIVE SAID ANALOG VOLTAGE AND SAID REFERECNE VOLTAGE, SAID SECOND COMPARISON MEANS OPERATING TO COMPARE SAID ANALOG AND REFERENCE VOLTAGES AND INCLUDING MEANS TO PROVIDE A STOP PULSE TO TERMINATE THE FLOW OF SAID CONSTANT FREQUENCY SIGNALS AT A SECOND PREDETERMINED TIME AFTER SAID REFERENCE VOLTAGE HAS REACHED A POINT OF EQUAL VALUE WITH SAID ANALOG VOLTAGE, SAID SECOND PREDETERMINATED TIME BEING EQUAL TO SAID FIRST PREDETERMINED TIME WHEREBY SAID COUNTING SYSTEM IS CAUSED TO OPERATE FOR A TIME PERIOD WHICH IS A FUNCTION OF THE VALUE OF SAID ANALOG VOLTAGE.
