Description

one

The invention responds to IK measurement technology and can be used in measuring impulse voltages.

The well-known amplitude-time converter contains a charge device connected to an accumulator capacitor, a current stabilizer, a discriminator, and a terminal, a pulse shaper, which possesses horns that depend on the waveform.

The purpose of the invention is to eliminate this drawback. For this, the input of the time-converter is connected via a pulse shaper to the control input of the current stabilizer and to the input of the coincidence circuit, the other input of which is connected to the output of the interval discriminator.

FIG. 1 shows a block diagram of the proposed converter; in fig. Chart 2 diagrams of various positions at various points of the circuit.

The input / converter is connected to the inputs of the charge device 2 and the driver 3 pulses. The output of the charging device is connected to a current stabilizer 4, a storage capacitor 5 and an interval discriminator 6, the output of which is connected to one input of the matching circuit 7, another IKOTO input is connected to the output of the driver, which is also connected to the control current stabilizer 4. Output

matching circuit 7 is the output of the converter.

When a measured pulse arrives at the input I of the transducer, the former 3 generates a pulse that closes the current stabilizer 4 and prohibits the passage of impulses from the discriminator 6 into the converter output. The charge device 2 charges the storage capacitor 5 to the amplitude of the measured pulse.

When the measured pulse decays, the signal of the discriminator 6 begins to form. With the end of the measured pulse, the pulse of the driver 3 is accumulated; stabilizer 4

the current is opened and a resolving impulse is fed to the coincidence circuit 7. The coincidence circuit 7 outputs a differential pulse determined by the discriminator of the interval b and the former 5 to the converter output.

The diagram of the folders (see Fig. 2) shows: a - measured impulse; b - impulse at the output of the imaging device 3 in - ILMPulse at the output of the charge device 1; g - pulse at the output of the discriminator 6; d is the pulse at the output of the converter.
