The device works as follows.

The pulse from the clock generator 1 is started by the clock distributor 2, switched on to circulate the number of the ring register unit 3 and the trigger of the memorized transfer 4.

If the block of elements And is open, then in the circuit the decimal adder 6 - the block of ring registers 3 circulates the number previously fixed parallel to the tetrad within the tetrad code. According to the available command, the Input is tilted into "1 trigger of input 15 memorization, which allows the pulse distributor 2 to pass through the AND 13 element of the k-th. This emulsion taps into" 1 mode switching trigger 14,

at the same time (fe + 1), (/ g + 2), ..., (/ g + /) - mimulsa MI through contacts, 2, ..., n input switches 12, encoder 7 and decimal adder 5 In the block of ring registers 3, the tetrado binary-decimal codes of numbers entered by the input contacts 12 input switches (/ is the number of bits of the number entered), (/ g- | - /) —th pulse of the clock distributor 2 overturns

"About the trigger memorization of input 15 and the trigger switch modes 14. Input on this channel is stopped, and the entered number circulates in the ring register unit 3. Poteitsialy located in this cycle on

the output of the tenth adder 5 of the tetrad through the decoder 8 and the switch 9 opens the corresponding cathodes of the block of digital indicators 10, one of which is ignited by the discharge of the capacity of the first switch 11,
