и на первом выходе f_1j релятора 1₁ будут определяться рекуррентными выражениями:The work of the proposed rank selector is as follows. The analogue signals (voltages) x ₁ , ..., x _{n + 1} ∈ (x _min , x _max ) to be processed are fed to the first information inputs of the relators 1 ₁ , ..., 1 _n and the third information input of the relator 1 _n ; digital signals y ₁ , y ₂ ∈ {0, 1}, respectively, are fed to the first and second training inputs of the selector (Fig. 2). When y ₂ = 1 (y ₂ = 0), devices 3 ₁ , 3 ₃ and 3 ₂ , 3 ₄ operate respectively in the sampling (storage) and storage (sampling) modes. If at the control inputs of keys 2 ₁ , 2 ₂ , 2 ₃ , ..., 2 ₆ , 2 ₇ , 2 ₈ there is a logical "1" (logical "0"), then the keys 2 ₁ , 2 ₃ , 2 ₅ , 2 _{7 are} open (closed), and the keys 2 ₂ , 2 ₄ , 2 ₆ , 2 _{8 are} closed (open). Therefore, the voltage at the second output f _{(i + 1) j of the} relay 1 _i

and at the first output f _{1j of the} relator 1 ₁ will be determined by recurrence expressions:

f _{(n + 1) j} = f _{(n + 1) (j-1)} ^ f _{n (j-1)} ;

...

f _ij = (f _{i (j-1)} ∨ ... ∨f _{(n + 1) (j-1)} ) ^ f _{(i-1) (j-1)} ;

...

f _1j = f _{1 (j-1)} ∨ ... ∨f _{(n + 1) (j-1)} ,

есть номер периода T_j сигнала y₂ (фиг.2), k=n+2-r, r∈{1,...,n+1} есть ранг сигнала х^(r) ∈ {х₁,...,х_n+1} х⁽¹⁾min{х₁,...,х_n+1},..., х⁽ⁿ⁺¹⁾max(х₁,...,х_n+1)); f_i0=x_i; f_(n+1)0=x_n+1.Where

is the period number T _{j of the} signal y ₂ (Fig. 2), k = n + 2-r, r∈ {1, ..., n + 1} is the rank of the signal x ^(r) ∈ {x ₁ , ... , x _{n + 1} } x ⁽¹⁾ min {x ₁ , ..., x _{n + 1} }, ..., x ^{(n + 1)} max (x ₁ , ..., x _{n + 1} )) ; f _i0 = x _i ; f _{(n + 1) 0} = x _{n + 1} .

Thus, at the outputs f _{ij, the} rank selector reproduces the operations

f _{(n + 1) j} = x ⁽¹⁾ = mix (x ₁ , ..., x _{n + 1} ) for j = n + 1

f _nj = x ⁽²⁾ for j = n,

...

f _1j = x ^{(n + 1)} = max (x ₁ , ..., x _{n + 1} ) for j = 1

according to which its adjustment to extract from the set {x ₁ , ..., x _{n + 1} } the signal x ^{(r) of} any given rank r∈ {1, ..., n + i} is carried out without any structural changes by the corresponding the number of periods T _{j of the} signal y _{2. The} above information allows us to conclude that the proposed rank selector has the same functionality compared to the prototype, but with lower hardware costs, since to construct this rank selector, 2 (n-1) fewer keys are required and 2 (n-1) fewer sampling / storage devices eniya.

Thus, the above information indicates the following conditions are met when using the claimed device:

- a tool embodying the claimed device in its implementation is intended for use in industry, namely in the field of automation and analog computing as a functional unit of analog computers, automatic regulation and control means, analog processors and
