The drawing shows a diagram of the device.

The device contains three counters 1-3, groups of 4-6 elements AND, registers 7, 8, adder 9, elements AND 10, 11, elements OR 12, 13, shift register 14, driver 15 pulses, three blocks 16, 17, 18 subtraction, element NOT 19.

The device works as follows.

The counting input of the counter 3 receives a signal with a frequency of E,

Each transfer pulse of this counter records the return code to the coefficient _t applied to the groups of inputs of group 6 elements I, and thus the output of counter 3 results in a sequence of pulses with a frequency of £, / k _g In subtraction blocks, the difference between the frequencies arriving at their inputs is obtained . The output of block 16 subtraction receive a signal with a frequency equal to ^ - £ _β , at the outputs of blocks 17 and 18 subtractions receive, respectively, the frequency and. And at the output of block 18 subtraction is also obtained the sign of the frequency difference, because frequency value can be either greater or less than

14 shifts, the counters 1 and 2 are sequentially reset, the code is written to _g in counter 2 and code d N = ¹ + ZD from register 8 to counter 1 (Ν ¹ is the code in ^-5 counter 1 at the end of the previous device operation cycle). five

The device has two modes of operation.

In the first mode, a potential corresponding to “O” is established at the input of the element NOT 19. At the same time, the U element 11 is closed to pass the signal coming from the output of block 18 subtraction, and the element 10 opens to pass a signal with frequency% "-ι ' ^{from the} output of block 17 subtraction through the element OR 12 to the counter input of counter 1 The counting input of counter 2 receives a signal with a frequency of 6,. Counters 1 and 2 begin to simultaneously type in information with frequencies of 20 arriving at their counting inputs.

Counter 2 operates in the subtraction mode: when it is zeroed, the transfer signal from the output of counter 2 through the pulse shaper 15 is sent to the 25th input of the register 7, recording the contents of counter 1 into it, and through the OR 13 element - to the input of the "1" register 14 shift , making record "1" in its younger category.

Counter 2 determines the dialing time. information in the counter 1, equal ZV / ZD

The code in counter 1 is determined by the expression

From this moment the described measurement cycle automatically repeats.

The code from the outputs of the digits of the counter 1 is given to the inputs of the digits of the adder 9, where it is compared with the code arriving at other inputs. adder 9 with block job to _g (not shown). The current value of 45 code, dialed in each cycle described above by the counter 1, is added up in the adder 9 with the code of the AP.

When comparing the codes at the output of the sum- $ d of the mator 9, a transfer signal arises, used, for example, in the material loading scheme for switching off the feeder. When a signal arrives at the "Record" input of register 8, the register 8 registers the sum of the N codes of counter 1 and the ZD task block, which is stored until the next receipt of the "Record" signal in register 8.

The full cycle of the device operation, determined by the time interval between the “Record” signal arrivals to the register 8, contains several measurement cycles, the duration of which is set by the counter 2.

The operation of the device in the second mode is similar to that described. The difference is that the potential corresponding to "1" is established at the input of the element NOT 19. This closes the element and 10 and opens the element And 11, with the result that the counter input 1 through the elements 11 and OR 12 from the output of the block 18 subtraction receives a signal with a frequency of -14.
