FIELD: measurement equipment.SUBSTANCE: device comprises an input device, a quartz generator, a shaping device, a frequency divider, a control device, a time selector, a counter, a decoder. At the same time the outlet of the first shaping device is connected with one inlt of the time selector, the second inlet of which is connected to the outlet of the control device, outlets of which are also connected to the inlets of the pulse counter, frequency divider, decoder, the inlet of the control device is connected to the outlet of the frequency divider, the outlet of which via the second shaping device is connected to the outlet of the quartz generator of the reference frequency, the outlet of the time selector is connected with the inlet of the pulse counter, the outlet of which is connected to the inlet of the decoder. Additionally the device comprises downstream the inlet device two integrators, two delay lines and two summators. At the same time the outlet of the inlet device is connected to the inlet of the first integrator, the outlet of which in its turn is connected to the inlet of the first summator and the inlet of the first delay line, the outlet of the first line of delay is connected to the inlet of the first summator, the outlet of the first summator is connected to the inlet of the second integrator, the outlet of which in its turn is connected to the inlet of the second summator and the inlet of the second delay line, the outlet of the second delay line is connected to the inlet of the second summator, the outlet of the second summator is connected to the inlet of the first shaping device.EFFECT: higher accuracy of measurement.2 dwg |
