A device for estimating the dispersion of parameters contains information input 1, start 2, a group of IZ elements, a trigger 4, a register 5, an OR 6 element, a HE 7 element, a pulse shaper 8, OR 9 and 10 elements, AND 11 and 12 element groups , drivers 13 and 14 pulses, registers 15 and 16, comparison blocks 17 and 18, elements AND 19-21, element OR 22, driver 23 pulses, indication blocks 24 and 25, delay element 26 and element 27.

The device works as follows.

Information messages in a binary or binary-decimal parallel code are sent to the inputs I of the device, and the input device 2 is reset to the initial state, the moment of arrival of this pulse is a reference point in time. The impulse from input 2 triggers 4, is zeroed, a high potential is established at its zero output, which through the element OR 9 and the driver 13 zeroes the register 15, through the element OR 10 and the driver 14 and zero the register 16, through the elements OR 9 or 10 , 22 and shaper 23 zero register 5. If there is high potential at zero output of flip-flop 4 through element RSHI 9, elements AND 11 are opened through second inputs and through element OR 10 - elements 12 And when register 5 is zero through element OR 6 and element NOT 7 elements are open And 3. The first information The message through the input is elementary And 3 is fixed in register 5, and from its output through open elements And 11 is rewritten into register 15 and through open elements And 12 into register 16. Register transition .5 volts. condition.

different from zero, i.e. when recording an informational message, distinguishes the OS from the nudy in all its bits, causes the appearance of a high potential at the output of the element OR 6, which through the element NOT 7 elements AND 3 at the second inputs are closed, and the leading edge of the high potential pulse from the output of the element OR 6 through the driver 8, the trigger 4 is transferred to a single state and a low zero potential is set at its output; The contents of register 15 are indicated by the display unit 24, and the contents of register 16 by block 25. The contents of registers 5 and 15 are compared by comparison block 17, and the contents of registers 5 and 16 by comparison block 18. At the output Less than the comparison block, a high potential is established only under the condition that the contents of register 5 modulo less than the contents of register 15, and the potentials Equal and More of 17 remain low potentials, the Equal output of block 17 is set to high potential with equality the contents of the registers 15 and 5, while at the outputs of the Less and More are kept low potentials, and the output of the More block 17 is set to a high potential provided that the content of the register 5 is over the content of the register 15, while the Outlets are Less and Equal while remaining under low potentials. At the output Less of block 1B, a high potential is established with the contents of register 5 less than the contents of register 16, Equal - if the contents of registers 5 and 16 are equal, and More - if the contents of register 5 exceed the contents of register 16, and the other two outputs of the block 18 remain at low potential. Thus, at the outputs of blocks 17 and 18, a corresponding signal appears on the contents of register 5 compared to the contents of registers 15 and 16, respectively. Based on the comparison of the initially recorded message, the current value of the parameter at the outputs are set to high potentials, which through AND 20, OR 22 and shaper 23 null the register 5, and through the elements OR 6 and NOT 7, the elements AND 3, the contents of registers 15 and

16 is saved. The next message is again through inputs 1 and elements 3 fixed by register 5. If the value of the newly arriving parameter is equal to the contents of registers 15 and 16, the procedure is repeated and if a 1 t a, where a is the value of the initially recorded parameter value, then a l, at the outputs of Less blocks 17 and 18 high potentials are established. The Smaller signal from the output of block 17 through the OR element 9 zeroes the register 15 and fixes the parameter a in it, where a is the value of the obsolete parameter in the register 15 and, besides, through the element OR 22 and the former 23, the register 5 is zeroed again. When a. A high potential pulse from the output of the More block 18 through the element OR 10 and the driver 14 sets the register 16 to zero and the value of the parameter a, -7 is fixed in it.

 a, and through the element OR 22 and form-. world world 23 zeroes register 5. Assuming a, j. and a, where a ,. - the contents of register 5; - the contents of register 15; a - the contents of register 16, high potentials are set at the output of More block 1 7 and at the output Less than block 18, shaper 23 zeroes register 5, and the contents of registers 15 and 16 remain.

The process can be repeated indefinitely, and at the outputs of registers 15 and 16 the current values of the lower and upper limits of the dispersion field of the sample of monitored parameters will be fixed.
