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, Fig. 1.3a on p.15 in the book Potemkin IS Functional units of digital automation. M: Energoatomizdat, 1988), which reproduce the operation supramed (τ ₁ , τ ₂ , τ ₃ ), where τ ₁ , τ ₂ , τ ₃ are the durations of three positive pulse signals synchronized along the leading edge.

The reason that impedes the achievement of the technical result indicated below when using known pulse selectors is limited functionality due to the fact that seven pulse signals cannot be processed.

The closest device of the same purpose to the claimed invention in terms of features is the pulse selector adopted for the prototype (Fig. 3.26 on p.125 in the book: Reference on digital computing. Malinovsky B.N., Aleksandrov V.Ya., Boyun V. P. et al. / Edited by B.N. Malinovsky, Kiev: Technique, 1974), which contains a resistor and reproduces the supramed operation (τ ₁ , τ ₂ , τ ₃ ), where τ ₁ , τ ₂ , τ ₃ is the duration of the positive impulse signals x ₁ , x ₂ , x ₃ ∈ {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 due to the fact that seven pulse signals cannot be processed.

The technical result of the invention is to expand the functionality by providing playback of the supramed operation (τ ₁ , ..., τ ₇ ), where τ ₁ , ..., τ ₇ are the durations of the positive pulse signals x ₁ , ..., x ₇ ∈ {0,1}, synchronized on a rising edge.

The work of the proposed pulse selector is as follows. At its first, ..., seventh inputs, positive pulse signals x ₁ ... x ₇ ∈ {0,1}, corresponding to the duration τ ₁ , ..., τ _7, respectively, synchronized on the leading edge, are supplied. If a logical “1” or a logical “0” acts on the control input of all keys of an arbitrary group, then each even key of this group is respectively closed or open, and each odd key is respectively open or closed. Thus, the pulse signal at the output of the proposed pulse selector is determined by the expression

where ·, ∨, ¯ are symbols of conjunction, disjunction, inversion. According to (1), we have

$$Z=\{\begin{array}{l}\mathrm{one}PR\mathrm{and}{\displaystyle \sum _{q=\mathrm{one}}^7{x}_q\ge 3}\\ 0PR\mathrm{and}{\displaystyle \sum _{q=\mathrm{one}}^7{x}_q<3}\end{array}.$$

Therefore, the selector (figure 1) will reproduce the operation τ _Z = supramed (τ ₁ , ..., τ ₇ ) (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 processing of seven pulse signals.
