The first, second, third and fourth inputs of voltage-4 converter are connected respectively with resistor 22, resistor 21, control inputs of the second 20 and first 19 keys.

The random pulse generator works as follows.

Before the device starts operating, a pulse is applied to the installation bus (Fig. 2a), which sets the trigger 6 into one state. At the second output of the device (direct output of the trigger 6), a single signal Sphi-2p is set. The initial setup signal briefly through the elements OR 11 and 12 (Fig. 2c, d) opens the keys 20 of the voltage-time converters 4 and 5. On the capacitors 18 of these converters, the instantaneous values of the random voltage of the generators 1 and 2 of the random voltages, respectively, are stored.

At the time of arrival of a single signal on the bus 15 Start (Fig.26)

the device is triggered by an element 14 (fig. 2d), a key 19 of a voltage converter 4 — time is opened j its capacitor 18 begins to integrate the voltage of the source 3 of the reference voltage. The instantaneous value of the random voltage at the output of the converter 4, the voltage time (Fig. 2g) is gradually reduced. As soon as the output voltage of the converter

l ijprine - prem will become equal to zero, the threshold element 7 (Fig.2i) is triggered, a single impulse from the output of which translates trigger 6

(Fig 2p, p) to the zero state. Thus, a pulse of random duration is formed at the second output of the random pulse generator. The pulse of the threshold element jg 7 through the delay element 9 (fig. 2m) opens the key 20 of the converter A voltage: - the time and on its capacitor 18 is filled with a new

instantaneous value of random voltage - | with tea voltage, the output of which

When the trigger 6 is switched to the zero state, a single signal from the first output opens (Fig. 2e) the key 19 of the converter 5 voltage-time, which converts (Fig. 2c, k, l, n) the instantaneous value of the random 25 generator voltage 2 random voltages, in the duration of the pause at the second generator output. ,
