FIG. 1 shows the device, the first embodiment; Fig, 2 is the same, the second option. The device contains elements 1 of the memory of the first group, outputs 2 elements 2И-OR of the first group, elements 2И-OR 3 of the first group, bus 4 permissions for counting, shaper 5 of the time interval, first inputs 6 elements 2И-OR of the first group, first key 7, bus 8 for output channel resolution, control block 9, first element OR 10, first trigger 11, pulse generator 12, first counter 13, memory block 14, first and second inputs 15 and 16 of the memory block, second element OR 17, second counter 18, the second key 19, the second trigger 20, the elements 2I-OR 21 of the second group, the first inputs 22 elements 2I-OR of the second group, outputs 23 elements 2I-OR of the second group, elements 24 of the memory of the second group. The device in the first embodiment works as follows. The data in the pulse number code is fed to the inputs of elements 2I-OR 3 of the first group. Before operation, the memory elements 1 and the memory unit 14, the first trigger 11, the first counter 13 and the time interval imaging unit 5 are reset with a signal from the control unit 9 (the initial setup circuit is not shown to simplify the drawing). The operation starts with the start of the time interval imaging unit 5 by the signal from the control unit 9. The output of driver 5 is fed to the counting bus 4. At the same time, from the outputs of 2 elements 2И-ШШ 3 to the inputs of elements 1 of the memory of all channels, data begin to arrive in the form of pulses distributed in time, generally randomly. The time interval is chosen so that at the maximum frequency of the input signals and the specified width of the first memory elements 1 of the first group, the memory elements do not overflow. After the end of the reference time interval, the signal to the output of the driver 5 is removed. Then, from the output of the control unit 9, the output resolution signal is received over the bus 8 of the channel to the input 6 of the elements 2I-OR 3 and the first trigger 11 is simultaneously set to one state. The output signal of the first trigger 11 opens the first key 7, and the pulses from the generator 12 pulses and the overflow of the memory element 1 begin to flow to the input of the first counter 13, to the input 6 of the elements 2I-OR and to the input of the memory 1 of the selected channel. The overflow signal is fed to the input of the first element OR 10 and to the reset input of the first trigger 11. The first trigger 11 is reset, closing the first key 7 and stopping the flow of pulses from the generator 12 pulses to the input of the first counter 13 and the memory element 1. The contents of the first counter 13 at this moment correspond to the number of pulses accumulated by p element 1 of the memory during the reference time interval. The interrogated memory element 1 is in the initial state. Further, according to the signals of the control unit 9 supplied to the inputs 15 and 16 of the memory unit 14, the data from the counter 13 is transferred to the corresponding cell of the unit 1D. The output process is repeated for all channels in turn. The device according to the second variant operates as follows. The operation starts according to the signal outputted from the control unit 9 to the shaper 5 time intervals, the latter issues a signal to the counting resolution bus 4 and from it to the inputs of the elements 2I-OR 13 and 21 of the first and second groups. Elements 1 and 24 of the memory of all channels simultaneously accumulate data arriving at the inputs of elements 2I-OR 3 in a number-pulse code. At the same time (after the lower bits of the memory elements 1 of a channel overflow), the data is transferred through the 2I-OR 21 elements in the presence of a signal on the counting bus 4 to the elements 24. Next, the data is output to the memory block 14 . In this case, from the control unit 9, a signal is fed to the bus 8 of the corresponding channel and from it to the second inputs 22 of the elements 2I-OR of the first and second D) FCP. The signal simultaneously sets the first and second triggers 11 and 20 to the Yaye unit state. Both triggers 11 and 20 output signals to the inputs of the first and second keys 7 and 19 open both keys, and from the output of the first key 7, the pulse generator 12 pulses start to flow to the input of elements 2I-OR 21 of the second group and the input of elements 24 of memory of the second group of the interrogated channel, as well as the input of the first counter 13. The signal from the output of the second key 19 is fed to the input of element 2И-OR 3, from output 2 of which the signal goes to first time entry p yes - 1 memory element of the same channel. After the memory element of the first group overflows, the signal through the second element OR 17 is fed to the reset input of the second trigger 20, which closes the second key 19 on the first input, and the flow of the generator pulses 12 to the input of the second counter 18 stops. Likewise, regardless of the previous (after the memory element 24 of the second group overflows), the signal through the first element OR 10 is fed to the reset input of the first trigger 11, which closes the first key 7 on the first input, and the flow of pulses to the input of the first counter 13 stops. At this point, the second counter 18 contains the number of pulses corresponding to the number accumulated during the reference time interval in the lower bits of 1 memory of the first group, and the first counter 13 contains the number corresponding to the accumulated batteries of the second group in the high bits of memory 24. . Then, the contents of the first and second counters 13 and 18, according to signals from control unit 9, arriving at inputs 15 and 16, are entered into the corresponding cell of memory unit 14. The output process is repeated for all channels in turn. The introduction of a pulse generator and two triggers into the device for inputting information, as well as the introduction of elements 2И-OR with their connections to each channel, ensure the performance of the system without loss of information.
