AbstractAbstract
[en] A comparator of numbers expressed in the natural binary system, working in parallel, has been produced. This makes it possible to ascertain whether an unknown number X is smaller or greater than a given number A; the case where X = A is not in evidence. The apparatus uses medium quality transistors and has a response time of the order of 1 μs. A combination of two comparators working together forms a ''conditioner'' which identifies the condition A < X < B. By making certain adjustments, the limits can be contained within the conditioning interval. (author)

Un comparateur de nombres exprimes dans le systeme binaire naturel, fonctionnant en parallele, a ete realise. Il permet de reconnaitre si un nombre inconnu X est inferieur ou superieur a un nombre donne A, l'egalite X = A n'etant pas mise en evidence. L'appareil construit avec des transistors de qualite moyenne a un temps de reponse de l'ordre de 1 μs. L'association de deux comparateurs fonctionnant en coincidence constitue un < conditionneur> qui met en evidence la condition A < X < B. Moyennant certaines modifications, les bornes peuvent etre incluses dans l'intervalle de conditionnement. (author)[es]

AbstractAbstract
[en] The application of superconducting direct-current comparators to the measurement of resistance ratios is described. One comparator consists of a binary set of ratios between 1:1 and 160:1 providing for self-calibration by a buildup procedure. A second comparator exhibiting discrete ratios of 1:1, 10:1, and 100:1 is also described. Ratio uncertainty of less than 1 part in 109 is achieved by enclosing the ratio windings in overlapping toroidal superconducting shields. Superconducting quantum interference devices serve as flux sensors for the comparators. One of these current comparators is used to calibrate a 100:1Ω resistive divider, which at a current of 10 mA exhibits a self-heating error of 0.0023 ppm

AbstractAbstract
[en] A digitization scheme of sub-microampere current using a commercial comparator with adjustable hysteresis and FPGA-based Wave Union TDC has been tested. The comparator plus a few passive components forms a current controlled oscillator and the input current is sent into the hysteresis control pin. The input current is converted into the transition times of the oscillations, which are digitized with a Wave Union TDC in FPGA and the variation of the transition times reflects the variation of the input current. Preliminary tests show that input charges < 25 fC can be measured at > 50 M samples/s without a preamplifier.

AbstractAbstract
[en] The ac and dc errors of cryogenic current comparators with toroidal-shield configurations are reported. Based on these experiments and on theoretical considerations, geometric parameters of the superconducting shields could be determined, which govern the errors. These results may be used for the construction of cryogenic current comparators with predictably low errors. It seems to be possible to decrease the dc error far below the present resolution limit of 3x10-11

AbstractAbstract
[en] A simple pulse low-level discriminator with integral discrimination on the basis of the K521SA3 comparator is described. The discriminator can be used for registration of pulses of >= 0.1 μs duration and amplitude of >= 1 mV. The amplitude of input pulses should not exceed amplitudes of supply voltages
