FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment and can be used for constructing digital converters of single nanosecond time intervals. Converter has a recirculator of start-pulse and a recirculator of stop-pulse, made on element OR, first input of which is connected to bus "stop-pulse" of the converter, second input - with the output of the delay line of stop-pulse, and the output - with the first input of an element AND, output of which is connected to the input of the delay line of stop-pulse and to the inverting input of pulses counter. Recirculator of start-pulse has an element OR, first input of which is connected to bus "start-pulse" of the converter, second input - with the output of the delay line of start-pulse, and the output - with the first input (m+1)-of the input element OR and with the input of the m-discharge delay line, m-outputs of which are connected to the D-inputs of appropriate m D-triggers and to the corresponding inputs (m+1)-of the input element OR, output of which is connected to the C-input of additional D-trigger and to the first input of the element AND, output of which is connected to the input of the start-pulse delay line, and the second input is connected to the second input element AND of the stop-pulse recirculator and with inverting output of additional D-trigger, D-input of which is connected to inverting input of the pulses counter of the stop-pulse recirculator, and the direct output - to the C-inputs of m-D-triggers, R-inputs of which are connected to the control input of the pulses counter 5, with R-input of additional D-trigger and with bus "initial plant" of the converter. At that the stop-pulse delay line of the stop-pulse recirculator has delay time equal to delay time of the start-pulse delay line of the start-pulse recirculator.EFFECT: technical result is in increase of conversion performance m times.1 cl, 2 dwg |
