Title: Improvements in and relating to digital voltmeters

IPC: H03M1/00
Filed: 1961-08-24
Abstract: 950,647. Electric selective signalling systems. SOLARTRON ELECTRONIC GROUP Ltd. Aug. 24,1962 [Aug. 24, 1961],No. 30582/61. Heading G4H. In an analogue to digital converter, particularly for the measurement of voltage, and hence of current, capacity or resistance, the voltage to be converted is applied to the input of an integrating amplifier which feeds a threshold unit. When the threshold is exceeded a clock pulse generator allows reference voltage pulses to be fed to the amplifier input in opposition to the unknown voltage until the output is reduced below the threshold. The voltage pulses are counted over a period of time determined from the pulse generator, and the counter shows the value of the voltage measured by illuminating selected numerals. In a first embodiment, the unknown voltage at 10 feeds integrating amplifier 16 which is also fed with zero volts or a reference voltage by way of transistors 32, 34, or 38,40. Units 18,19 detect respectively whether the output of amplifier 16 exceeds a negative or a positive threshold, and control gates 22, 24 which permit clock pulses from unit 26 to trigger bistable units 28 or 30 whenever a threshold is exceeded, and thus impress either zero volts or reference volts on the amplifier input. The clock pulses also feed a unit 48 which closes switch 12 for a fixed period. The number of pulses fed to the amplifier input is counted by counter 52. If the two inputs to counter 52 cause it to count forwards the mean value of a D. C. or A. C. voltage is indicated. If, however, one input causes forward counting and the other backward counting, the D. C. level of an A. C. voltage is indicated. The operation may be modified somewhat in that if the unknown voltage is applied continuously, i. e. if switch 12 is maintained closed, counter 52 is allowed to count only over a period determined by way of unit 44.
