The pulse signal pseudorandom generator relates to instrument making and can be used in the breaking process, debugging and dosimetry equipment check-up for output signal simulation of dosimetric detectors of various types with account of their dead times. The generator comprises a pseudorandom number forming unit, the first comparison circuit and the first AND logic element, the first input being connected to the first comparison circuit output and the second input is connected to a device clock input and a pseudorandom number forming unit input, the parallel inputs being connected to the first group of the first comparison circuit, the second group of inputs being connected control code charges setting an output pulse medium frequency value. In addition there is a second comparison circuit, a counter, a RS-flip-flop, the second positive AND gate and two positive OR gates, the first input of the first ones is connected with the first input of the second positive OR gate and a device control input and the output is connected to a counter reset input, the counter input being connected to a device clock input and parallel outputs are connected to the first group of the second comparison circuit inputs, the second group being connected to control code charges setting a dead time value of detector and the output is connected to flip-flop S-input, the R-input being connected to a device output and the second input of the first positive OR gate and the output is connected to the second input of the second positive OR gate, the output being connected to the first input of the second positive AND gate, the first input being connected to the first AND positive gate output and the output is connected to a device output. The technical result is opportunity to control an output momentum flux and at account of it makes its enhancement. |
