Description

 The invention relates to a pulse technique and can be used to build automation, functional units of control systems, etc.

Pulse selectors are known (see, for example, RF Certificate 21679, class G 06 G 7/25, 2002), which can be used to reproduce the operation min (τ ₁ , ..., τ _n ) or operation max (τ ₁ , ..., τ _n ), where τ ₁ , ..., τ _n are the durations of the positive impulse signals x ₁ , ..., x _n , ∈ {0,1} synchronized along the leading edge.

The reason that impedes the achievement of the technical result indicated below when using known pulse selectors includes limited functionality, as well as low accuracy, due to the fact that parallel operations of min (τ ₁ , ..., τ _n ) and max ( τ ₁ , ..., τ _n ), as well as the fact that the maximum propagation delay time of a signal in known pulse selectors is determined by the expression t = (n-1) (t _C + t _L + t _S ), where t _C , t and _L t _S is the time delay of the comparator respectively, logical one element XOR and key.

The closest device of the same purpose to the claimed invention in terms of features is the pulse selector adopted for the prototype (Certificate of the Russian Federation 20593, CL G 06 G 7/25, 2001), which contains n closing and n opening keys and can be used to play operations min (τ ₁ , ..., τ _n ) or operations max (τ ₁ , ..., τ _n ), where τ ₁ , ..., τ _n are the durations of positive pulse signals x ₁ , ..., x _n ∈ {0,1} synchronized on the leading edge.

The reason that impedes the achievement of the technical result indicated below when using the prototype is limited functionality, as well as low accuracy, due to the fact that parallel operations of min (τ ₁ , ..., τ _n ) and max (τ ₁ , ..., τ _n ), as well as the fact that the maximum signal propagation delay time in the prototype is determined by the expression t = n (t _C + t _L + t _S ).

The technical result of the invention is the expansion of functionality by providing parallel playback operations min (τ ₁ , ..., τ _n ) and max (τ ₁ , ..., τ _n ), where τ ₁ , ..., τ _n - the duration of positive pulse signals x ₁ , ..., x _n ∈ {0,1} synchronized on the leading edge, as well as an increase in accuracy.

информационный вход которого образованы соответственно выходом n-го размыкающего ключа и управляющим входом i-ых замыкающего, размыкающего ключей.The specified technical result in the implementation of the invention is achieved by the fact that in the pulse selector containing n closing and n opening keys, in which the output of each previous opening key is connected to the input of the subsequent opening key, the peculiarity is that two resistors are introduced into it, the first a resistor is connected between the output of the nth closing key and the combined bus of zero potential, the input of the first disconnecting key, and the second resistor is between the output of the nth closing key and ennymi tuning input of the pulse selector, the first input of the locking key, the previous output of each locking key connected to the input subsequent locking key, and an output n-th locking key - the first output of the pulse selector, the second output and the i-th

the information input of which is formed respectively by the output of the nth opening key and the control input of the ith closing, opening keys.

Therefore, the claimed invention meets the condition of "novelty."

To verify the compliance of the claimed invention with the condition "inventive step", the applicant conducted an additional search for known solutions in order to identify signs that match the distinctive features of the claimed device from the prototype. The search results showed that the claimed invention does not derive explicitly from the prior art for the specialist, since the influence of the transformations provided for by the essential features of the claimed invention on the achievement of the technical result is not revealed from the prior art determined by the applicant, in particular, the following transformations are not provided for by the claimed invention:
- addition of a known product by any known part (s) attached to it according to known rules to achieve a technical result in respect of which the effect of such additions is established;

 The described invention is not based on a change in the quantitative characteristic (s), the presentation of such signs in relationship, or a change in its form. This refers to the case when the fact of the influence of each of these characteristics on the technical result is known, and new values of these signs or their relationship could be obtained on the basis of known dependencies and patterns. Therefore, the claimed invention meets the condition of "inventive step".

 Figure 1 presents a diagram of the proposed pulse selector. In FIG. Figure 2 shows the timing diagrams explaining the principle of its operation (for example, with n = 4).

информационный вход которого образован управляющим входом ключей 1_i и 2_i.The pulse selector contains closing keys 1 ₁ , ..., 1 _n , opening keys 2 ₁ , ..., 2 _n , resistors 3 ₁ and 3 ₂ , and a resistor 3 _{1 is} connected between the output of the key 1 _n and the combined bus of zero potential, the input of the key is 2 ₁ , and the resistor 3 ₂ is between the output of the key 2 _n and the combined tuning input of the pulse selector, the input of the key 1 ₁ , the output of each previous closing key is connected to the input of the subsequent closing key, and the output of each previous disconnecting key to the input of the subsequent disconnecting key, key outputs 1 _n and 2 _{n are} connected respectively to the first and second outputs of the pulse selector, i-th

the information input of which is formed by the control input of keys 1 _i and 2 _i .

 The work of the proposed pulse selector is as follows.

либо x_i=0, то ключ 1_i соответственно замкнут либо разомкнут, а ключ 2_i соответственно разомкнут либо замкнут. Таким образом, импульсные сигналы на выходах селектора (фиг.1) определяются выражениями

Следовательно, предлагаемый селектор будет параллельно воспроизводить операции Z₁ = min(τ₁,...,τ_n) и Z₂ = max(τ₁,...,τ_n) (см. фиг.2).Positive pulse signals x ₁ , ..., x _n ∈ {0,1} with durations τ ₁ , ..., τ _n, respectively, are synchronized on the leading edge of its first, ..., nth information inputs, respectively ; signal f = 1 is fixed at its tuning input. If x _i = 1

or x _i = 0, then key 1 _{i is} respectively closed or open, and key 2 _{i is} respectively open or closed. Thus, the pulse signals at the outputs of the selector (figure 1) are determined by the expressions

Therefore, the proposed selector will simultaneously reproduce the operations Z ₁ = min (τ ₁ , ..., τ _n ) and Z ₂ = max (τ ₁ , ..., τ _n ) (see figure 2).

The above information allows us to conclude that the proposed pulse selector has a wider functionality compared to the prototype, as it provides parallel playback of the operations min (τ ₁ , ..., τ _n ) and max (τ ₁ , ..., τ _n ), where τ ₁ , ..., τ _n are the durations of positive pulse signals x ₁ , ..., x _n ∈ {0,1} synchronized along the leading edge, while the proposed pulse selector has a higher accuracy compared to the prototype , since the maximum delay time of the signal propagation in selector-bonded is determined by the expression t = t _S, where t _S - temporary key delay.

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 pulsed technology as a functional unit of automation systems, control, etc .;
- for the claimed device in the form described in the independent clause of the claims, the possibility of its implementation using the means and methods described in the application or known prior to the priority date is confirmed;
- a tool embodying the claimed invention in its implementation, is able to ensure the achievement of the perceived by the applicant technical result.

 Therefore, the claimed invention meets the condition of "industrial applicability".
