[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]
Se ha construido un comparador de cifras expresadas en el sistema binario natural que funciona en paralelo. Permite determinar si una cifra desconocida X es inferior o superior a una cifra dada A ; la igualdad X = A no se pone en evidencia. El aparato esta construido con transistores de calidad media y tiene un tiempo de respuesta del orden de 1 μs. La asociacion de dos comparadores que funcionen en coincidencia constituye un < condicionador> que hace evidente la condicion A < X < B. Merced a algunas modificaciones, los terminales pueden incluirse en el intervalo de acondicionamiento. (author)[ru]
Byl sozdan parallel'no vklyuchaemyj sravnitel' chisel, vyrazhennykh v natural'noj dvoichnoj sisteme. On daet vozmozhnost' opredelyat', yavlyaetsya li neizvestnoe chislo X bol'she ili men'she dannogo chisla A, ne vyyavlyaya ravenstva X = A. Apparat postroen na tranzistorakh srednego kachestva so vremenem srabatyvaniya poryadka 1 μs. Sparivanie dvukh dejstvuyushchikh po printsipu sovpadenij sravnitelej obrazuet ''konditsioner'', kotoryj vyyavlyaet uslovie A < X < b. Pri pomoshchi nekotorykh izmenenij v konditsionirovannyj interval mogut byt' vklyucheny promezhutochnye zazhimy. (author)Source

[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.

[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

[en] Voltage-ratio-meter is brilt according to amplitude-to-time conversion principle and forms at the output the time interval, proportional to two voltages ratio. Division maximal time is 10 ms, error is 0.1% at voltages change within 0.1-10 V interval. Measurement cycle is initiated by the external logical signal
