Description

 The invention relates to automation and analog computing and can be used to build functional units of analog computers, means of automatic regulation and control, analog processors, etc.

Rank selectors are known (see, for example, Fig. 4 in the book Volgin L.I. Complementary algebra and modeling of neural structures. - Tallinn: Academy of Sciences of Estonia, 1993, - 48 pp.), Which contain n relators and only select the signal ( n + 1) th rank (largest signal) of several analog signals x ₁ , ..., x _{n + 1} .

 The reason that impedes the achievement of the technical result indicated below when using known rank selectors is limited functionality due to the fact that the signal is not selected for any given rank r ∈ {1, ..., n + 1}.

The closest device of the same purpose to the claimed invention in terms of features is the rank selector adopted by the prototype (ed. St. USSR 1262531, class G 06 G 7/25, 1986), containing n relators, each of which is made in the form differential comparator, and performing selection from several analog signals x ₁ , ..., x _{n + 1} signal only (n + 1) -th rank.

 The reason that impedes the achievement of the technical result indicated below when using the prototype is limited functionality due to the fact that the signal of any given rank r ∈ {1, ..., n + 1} is not selected.

 The technical result of the invention is the expansion of functionality by ensuring the selection of n + 1 analog signal signals of any given rank r ∈ {1, ..., n + 1}.

Each relator contains the first, ..., eighth keys 2 ₁ , ..., 2 ₈ , the first, ..., the fourth sampling / storage device 3 ₁ ,. .., 3 ₄ , differential comparator 4, Boolean inverter 5, and the keys 2 ₁ , 2 ₃ , 2 ₅ , 2 ₇ and 2 ₂ , 2 ₄ , 2 ₆ , 2 _{8 are} made respectively closing and opening, first, ... , the fourth information and the first control inputs of the relator are formed respectively by the inputs of the keys 2 ₁ , ..., 2 ₄ and their control input, the outputs of the keys 2 ₁ , 2 ₂ and 2 ₃ , 2 _{4 are} connected respectively to the information input of the device 3 ₁ and the information input devices 3 ₂ , the recording inputs of which are connected to the input of the inverter 5 and form the second control input of the relator, inverting and non-inv the control inputs of the comparator 4, connected by the output to the control input of the keys 2 ₅ , ..., 2 ₈ , are connected respectively to the combined output of the device 3 ₁ , the inputs of the keys 2 ₅ , 2 ₈ and the combined output of the device 3 ₂ , the inputs of the keys 2 ₆ , 2 ₇ , the outputs of the keys 2 ₅ , 2 ₆ and 2 ₇ , 2 _{8 are} connected respectively to the information input of the device 3 ₃ and the information input of the device 3 ₄ , the outputs of which are the first and second outputs of the relator, respectively, and the recording inputs are connected to the output of the inverter 5.

V_ij = min(V_i(j-1), W_{(i-1) (j-1)});
W_ij = max(V_i(j-1), W_{(i-1) (j-1)}),
где

есть номер периода Т_j сигнала y₂ (фиг. 3), k = 2i+1-r, r ∈ { 1, . . ., i+1} есть ранг сигнала x^(r) ∈ {x_n+1, x₁,..., x_i} (x⁽¹⁾ = min(x_n+1, x₁, . . ., x_i), ..., x⁽ⁱ⁺¹⁾ = max(x_n+1, x₁, ..., x_i)); V_i0 = x_i; W₀₀ = x_n+1; W₁₀ = ...= W_(n-1)0 = x_max; W_0j = x_min.The work of the proposed rank selector is as follows. The second information inputs of the relators 1 ₁ , ..., 1 _n and the fourth information input of the relator 1 ₁ are fed the analog signals (voltages) x ₁ , ..., x _{n + 1} ∈ (x _min , x _max ) to be processed; at the fourth inputs of the relators 1 ₂ ,. . . , 1 _n and at the third input of the relay 1 ₁ are fixed, respectively, the reference voltage x _max and x _min ; digital signals y ₁ , y ₂ ∈ {0, 1}, respectively, are fed to the first and second tuning inputs of the selector (Fig. 3). With y ₂ = 1 (y ₂ = 0), devices 3 ₁ , 3 _2, and 3 ₃ , 3 ₄ operate respectively in the sampling (storage) and storage (sampling) modes. If at the control inputs of keys 2 ₁ , ..., 2 ₄ and 2 ₅ , ..., 2 ₈ there is a logical "1" (logical "0"), then the keys 2 ₁ , 2 ₃ , 2 ₅ , 2 _{7 are} closed (open), and the keys 2 ₂ , 2 ₄ , 2 ₆ , 2 ₈ open (closed). Therefore, the voltage at the outputs of the relay 1 _i ,

will be determined by recurrence expressions:
V _ij = min (V _{i (j-1)} , W _{(i-1) (j-1)} );
W _ij = max (V _{i (j-1)} , W _{(i-1) (j-1)} ),
Where

is the period number T _{j of the} signal y ₂ (Fig. 3), k = 2i + 1-r, r ∈ {1,. . ., i + 1} is the rank of the signal x ^(r) ∈ {x _{n + 1} , x ₁ , ..., x _i } (x ⁽¹⁾ = min (x _{n + 1} , x ₁ , ..., x _i ), ..., x ^{(i + 1)} = max (x _{n + 1} , x ₁ , ..., x _i )); V _i0 = x _i ; W ₀₀ = x _{n + 1} ; W ₁₀ = ... = W _{(n-1) 0} = x _max ; W _0j = x _min .

согласно которой его настройка на выделение из множества {x₁,..., x_n+1} сигнала x^(r) любого заданного ранга r ∈ {1,..., n+1} осуществляется без каких-либо структурных изменений соответствующим количеством периодов T_j сигнала y₂.Thus, at the output Z, the rank selector reproduces the operation

according to which its adjustment to extract from the set {x ₁ , ..., x _{n + 1} } a signal x ^{(r) of} any given rank r ∈ {1, ..., n + 1} 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 wider functionality compared to the prototype, as it provides selection from n + 1 analog signals of a signal of any given rank r ∈ {1, ..., n + 1}.

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, means of automatic regulation and control, analog processors, etc .;
