Abstract

1,179,309. Analogue/digital converter. VARIAN ASSOCIATES. 22 Sept., 1967 [28 Sept., 1966], No. 43311/67. Heading G4H. [Also in Division G1] In an electrographic recorder with an electronic analogue-to-digital converter arranged to convert a variable signal Ei applied to terminals 2 into digital form in order selectively to apply writing potential to electrodes 9 in an array across recording medium 11 and so to record the variable thereon, the converter includes a pulse generator 4, an electronic counter circuit for producing a reference signal Er whose amplitude is proportional to the number of pulses counted, means 3 comparing the signals Ei, Er to produce an error signal Ee which shuts off pulses from the generator 4 at zero error so that the count stops at a null balance count and electronic gates responsive to the null balance count selectively to apply writing potential to the electrodes 9. As shown in Fig. 1, the counter is a bidirectional shift register 7 with an array of flip-flops 6, of which one, 6<SP>1</SP>, has initially an output opposite to all the others and this opposite output can be made to travel round the ring a step for each pulse. The outputs of the flip-flops 6 are tied through diodes 13 to successively higher resistance points of a resistor 14 to produce successive values of Er and are also applied to gates 8. The gates 8 include transistors which take longer to switch than the flip-flops 6 so that only when the register 7 dwells on a null balance count can a transistor be biased to the conductive state and the gate 8 allow sufficient potential to pass between the corresponding electrode 9 and a common electrode 12 for writing on the intervening medium 11. A commutator, Fig. 5 (not shown), may be used to allow time sharing between several variables. Alternative counting and selecting circuits providing analogue-to-digital conversion are described with reference to Figs. 3 and 4 (not shown).
