FIG. Figure 2 shows timing input voltage pulses (a); the voltage on the first winding of the first transformer 5 (b); closing the opening contact of the first mifistor 1 (c); closing the closing contact of the first mythistor 1 (g); closing the opening contact of the second mifistor 2. (d); closing the closing contact of the second mifistor 2 (g); closing the opening contact of the third mythistor 3 and the group of output mythists A (l); closure of the closing contact of the third mifistor 3 and the group of output mifistors 4 (k).

The device works as follows.

According to the signal of the initial setup, which enters input 9 of the trigger, the electrodes of the first 1, second 2, third 3 mythistors are reset: the control electrodes are closed with the opening electrodes.

The counting input 8 starts to receive pulses (Fig. 2a). Due to the presence at the input of the first winding of the transformer 5 of the capacitor 11 in the first winding of the first transformer 5, a short pulse of negative polarity is formed from the input pulse cut, and a short pulse of positive polarity (Fig. 26) is generated on the front of the input pulse, in the third A current pulse is formed in the winding of the first transformer 5, which switches the first myth 1 to the closing state of the control electrodes with the closing electrode. This state of the first mifistor 1 (Fig. 2c, d) provides the supply voltage to the middle terminal of the first winding of the second transformer 6, through which current flows from the middle winding terminal to its end, since the third myth 3 control electrodes with a disconnecting electrode. This leads to the formation of a current in the third winding of the second transformer 6 of the same direction as in the first winding, under the action of which the second mythistor 2 switches to the closing state of the control electrodes with electrode am 1) 1.

Under the action of a short negative polarity pulse in the third winding of the first transformer 5, a current pulse is formed, which switches the first myth 1 to the closing state of the control electrodes with an open electrode. This state of the first mythistor 1 transfers the supply voltage to the middle terminal of the first winding of the third transformer 7, through which current starts flowing from the middle winding terminal to its end, since the second myth 2 is in the state of the control electrodes with the closing electrode, which leads to the formation of current in the third winding of the third transformer 7 and its output windings in the same direction as in the first winding, under the action of which the third mifistor 3 switches and you group 4-period mifistorov state circuit control electrodes with movable electrode.

Upon the arrival of the next pulse to the counting input 8 of the trigger, under the action of a short pulse of positive polarity, the first myth 1 switches to the closing state of the control electrodes with the closing electrode, which provides the supply voltage to the middle terminal of the first winding of the second transformer 6, which begins to flow the current is directed from the middle end of the winding to its beginning, since the third mythistor 3 is in the state of closing the control electrodes with the closing electrode. Under the action of this current in the third winding of the second transformer 6, a current flows in the same direction as in its first winding, which switches the second myth 2 to the closing state of the control electrodes with the tripping electrode. Thus, the second myth 2 returns to its original state. Under the action of a short negative polarity pulse, the first myth 1 switches to the closing state of the control electrodes with the trip electrode, which supplies the supply voltage to the middle terminal of the first winding of the third transformer 7. At the same time, as the second myth 2

in the state of the control electrodes with the opening electrode, the first winding of the third transformer 7 begins to flow a current directed from the middle winding terminal to its beginning, which in the third and output windings of the third transformer 7 leads to the formation of the same direction as in the first winding of the third transformer 7. Under the action of this current, the third mifistor 3 and the group of output mifistors 4 are switched to the 15th state of closing the electrodes with the opening electrode, returning to the initial state.
