due to the connection in the feedback circuit of the adder 2 of the corresponding feedback element of the dial floor of the switch 9. The adder 6 receives a signal equal to the signal module at the output of the adder 1, since the circuit of the generator of the module 3 is connected to the circuit between them erecting one of the squares and extracting the root from the radical expression.

The input signal received in the distributor 7 is registered by a counter, which controls the switching of the feedback elements in the switch 8 and 9, the adders 1 and 2, and also feeds the keys 12 and 11, through which the calculation results are printed after processing each implementation. When the characteristics of the main operator are raised, the discrete signal 2, corresponding to the standard deviation of the characteristic of its quality, from the output of the key 12 is fed to the input of the quadrant 14. From the output of the quadrant 14, the signal equal to B, through the signal the trigger 23, the key 13 enters the block 15. The results of the assessment of the quality of activity of the main operator are analyzed and the device is transferred to the study of the characteristics of the test operator

After stabilization of the determined statistical characteristics of the main operator. To do this, the researcher on the console 22 presses the switch 40, which provides for issuing control voltage to the key assembly of the node 27 of the block 15. Through the keys of the node 27, it is digitized in the converter. 26, the value 6 is written to the register 24 of the block 15. The numerical information from the outputs of the register 24 is converted into the corresponding voltage in the converter 25. Then the researcher on the panel 22 presses a button 42, by means of which the control voltage of the external power source is applied to the input of the trigger 23 , under the influence of which the switching 20 of the trigger 23 is performed. As a result, the key 13 is locked and the device is prepared for the investigation of the test operator.

The device at the time of the study of the characteristics of the main operator can work in automatic mode. In this case, it automatically terminates the process of investigating the main operator by closing the to key by a Stop command from the distributor 7 sales counter after a specified number of tests. By the same command, received at the input of the trigger 23, the block 15 is disconnected from the key output 12. In automatic mode, the switch 40 of the console 22 is closed. In this case, the last value of the implementation of the value b will be recorded in register 24 of block 15. The automatic mode of operation of the device is used in cases where the stabilization of the operating parameters of the main operator during the use of the "1st period of operation does not occur.

At the same time, in the process of examining the performance of the main operator, the pulses of the beginning of each realization come from the output of the distributor 7 pulses to the input of the distributor 21, where the key 37 is closed by the voltage of the output of the trigger 23, and the switch 37 is closed and opens

Thus, after the end of the study of the characteristics of the main operator, the output of the block 15 is voltage proportional to the variance of the quality characteristics of the main operator, and the counter 38 of the former 21 records the number of realizations of the main operator h.

The process of determining the characteristics of the operator's work, compared with the main one, is similar to the described process. In the process of determining the quality characteristics of the operator’s performance compared to the main ones, the number L of the necessary implementations is recorded in counter 29. When the characteristics of the compared operator are determined, the output proportional to 14 is removed, the voltage proportional to the square of the standard deviation of the quality characteristics of the activity & comparable operator. A voltage proportional to b is amplified by an amplifier 16 with a gain inversely proportional to the variance of the characteristics of the quality of activity of the main operator, the magnitude of which is stored in block 15. The output of the amplifier 16 removes the voltage proportional to the ratio, js O

The end of the study of the operator being compared by the researcher closes the switch 39 of the console 22, which provides the control voltage of an external source that opens the keys of the nodes 28 and 30. Signals from the outputs of the counters 29 and 38 are fed to the corresponding control inputs of the switch 31 of the former 21. In In accordance with the code signals of the counters 29 and 38, the switch 31 switches the resistances in the feedback circuit of the amplifier 32, which are selected so that the output voltage is directly proportional to the value of the function F of the distributor with (hj-1) and (degrees of freedom at the dependence level (1-o (). At the same time, the voltage proportional to the value of 5. (h, -1))), from the output of amplifier 32 goes to control input of amplifier 35 whose coefficient is set inversely proportional to 5
