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 patent 2595960, class H03K 5/00, 2016), which provide a choice of n positive pulse signals x ₁ , ..., x _n ∈ {0,1} synchronized on the leading edge having durations τ ₁ , ..., τ _n, respectively, of signal x _k , the duration of which is the mth largest after the minimum duration among τ ₁ , ..., τ _n , where n = 5, m = 3.

The reason that impedes the achievement of the technical result indicated below when using known pulse selectors includes limited functionality, due to the fact that it is not allowed to process signals x ₁ , ..., x _n with n = 6 and m∈ {3,4}.

The closest device of the same purpose to the claimed invention according to the totality of features is the pulse selector adopted for the prototype (RF patent 2517295, class H03K 5/26, 2014), which contains a resistor, keys, and provides a choice of n positive edge-synchronized pulse signals x ₁ , ..., x _n ∈ {0,1}, having durations of τ ₁ , ..., τ _n, respectively, of signal x _k , whose duration τ _k is the mth largest after the minimum duration among τ ₁ , ..., τ _n , where n = 5, m = 3.

The reason that impedes the achievement of the technical result indicated below when using the prototype is limited functionality due to the fact that it is not allowed to process signals x ₁ , ..., x _n with n = 6 and m∈ {3,4}.

The technical result of the invention is to expand the functionality by providing a choice of n positive impulse signals x ₁ , ..., x _n ∈ {0,1}, of duration _{n 1} , ..., τ _n, respectively, of signal x _k , duration τ _k which is the mth largest after the minimum among the durations τ ₁ , ..., τ _n , where n = 6, m∈ {3,4}.

the groups are connected respectively to the unit potential bus and the i-th input of the pulse selector, the output of which is connected to the output of the first key of the fourth group connected via a resistor to the zero potential bus, the peculiarity is that the fifth to fifth keys are additionally introduced into it , from the fourth to the seventh keys of the first group and the sixth key of the second group, the even and odd entered keys are made respectively opening and closing, in the jth (j∈ {1,5}) group, the input and output of the even entered key connected respectively to the input of the subsequent and output of the previous keys, the input of the first and the output of the sixth keys of the second group are connected respectively to the output of the first key of the first group and the input of the fourth key of the third group, and the inputs of the third, fifth and sixth keys of the second group are connected respectively to the outputs of the third, fifth and the seventh key of the first group, connected by inputs to the outputs of the first, third and fifth keys of the fifth group, the inputs of which are connected respectively to the unit bus, the sixth and seventh inputs of the pulse selector connected by the fifth input to the control input of all the keys of the fifth group.

In FIG. 1 shows a diagram of the proposed pulse selector. In FIG. 2 shows time diagrams explaining the principle of its operation.

группы соединены соответственно с шиной единичного потенциала, шестым, седьмым и r-ым входами импульсного селектора, выход которого соединен с выходом ключа 2₄₁, подсоединенным через резистор 1 к шине нулевого потенциала.The pulse selector contains a resistor 1 and twenty-four keys 2 ₁₁ , ..., 2 ₅₅ , which are grouped into five groups so that the first, second, third, fourth and fifth groups respectively contain seven keys 2 ₁₁ , ..., 2 ₁₇ , six keys 2 ₂₁ , ..., 2 ₂₆ , four keys 2 ₃₁ , ..., 2 ₃₄ , two keys 2 ₄₁ , 2 ₄₂ and five keys 2 ₅₁ , ..., 2 ₅₅ , moreover, the even and odd keys of the indicated groups are made respectively opening and closing, in each group, the even key output is connected to the previous key output, in each group except the fourth the previous even key input is connected entering the subsequent key, the key inputs 2 ₃₁ 2 ₃₃ 2 ₃₄ and outputs key 2 ₃₁ 2 ₃₃ are connected respectively to the keys outputs 2 ₂₁ 2 ₂₃ 2 ₂₅ and key inputs 2 _41, 2 _42, inputs and outputs key February ₁₁ , 2 ₁₃ , 2 ₁₅ , 2 _{17 are} connected respectively to the unit potential bus, key outputs 2 ₅₁ , 2 ₅₃ , 2 ₅₅ and key inputs 2 ₂₁ , 2 ₂₃ , 2 ₂₅ , 2 ₂₆ , and key inputs 2 ₅₁ , 2 ₅₃ , 2 ₅₅ and the control input of all keys of the rth

groups are connected respectively to the unit potential bus, the sixth, seventh and rth inputs of the pulse selector, the output of which is connected to the output of the key 2 ₄₁ , connected through the resistor 1 to the bus of zero potential.

The work of the proposed pulse selector is as follows. At its first, ..., fifth, sixth, and seventh inputs, positive pulse signals x ₁ , ..., x ₅ ∈ {0,1} with durations of τ ₁ , ..., τ _5, respectively, and signals of ₁ ∈ {1, x ₆ }, y ₂ ∈ {0, x ₆ } (x ₆ ∈ {0,1} is a positive pulse signal synchronized along the leading edge with signals x ₁ , ..., x ₅ and having a duration of τ ₆ . If a logical “1” or a logical “0” acts on the control input of all the keys of an arbitrary group, then each odd key of this group is respectively closed or open, and each even key is respectively open or closed. Thus, the pulse signal at the output of the proposed pulse selector is determined by the expression

there are symbols of conjunction, disjunction, inversion. According to (1)

for y ₁ = x ₆ , y ₂ = 0 or for y ₁ = 1, y ₂ = x _6, respectively, we have

or

Therefore, the selector (Fig. 1) for y ₁ = x ₆ , y ₂ = 0 or for y ₁ = 1, y ₂ = x ₆ selects the signal x _k ∈ {x ₁ , ..., x ₆ }, the duration τ _k which is respectively the third or fourth largest after the minimum among the durations τ ₁ , ..., τ ₆ (see, for example, Fig. 2).

The above information allows us to conclude that the proposed pulse selector has a wider functionality compared to the prototype, as it provides a choice of n positive pulse signals x ₁ , ..., x _n ∈ {0,1} with duration τ ₁ , ..., τ _n, respectively, of a signal x _k whose duration τ _k is the mth largest after the minimum duration among τ ₁ , ..., τ _n , where n = 6, m∈ {3,4}.
