The device operates as follows. Input pulses (for example, the first duration t1and the second duration t2(Fig.2,a)), an input frequency divider 1, which reduces the frequency of these pulses is doubled (Fig.2,b). The inputs of the first cell, 2 and 4 served the input pulses and the output signal from the divider 1, the output of the cell signal "1" is present during only the first input pulse (Fig.2).
