FIELD: electricity. SUBSTANCE: in supramed operation (τ1,…,τ7) τ1,…,τ7 there are lengths of positive pulse signals x1,…,x7∈{0.1} synchronised against the front edge. The device contains a resistor and twenty four keys grouped in six groups. EFFECT: implementation of supramed operation. 2 dwg
The invention relates to a pulse technique and can be used for building automation, functional units of the control systems and other Known pulse selectors (see, for example, rise on p.15 in the book Potemkin I.S. Functional units of digital automation. M.: Energoatomizdat, 1988), which reproduce the operation supramed (τ1τ2τ3), where τ1τ2τ3have a duration of three positive pulse signals that are synchronized on the leading edge. For the reason that impede the achievement of specified following technical result when using the known pulse selectors include limited functionality due to the fact that no Pets processing seven pulse signals. The closest device to the same destination to the claimed invention by the combination of features is adopted for the prototype pulse selector (RIS on s in the book: Handbook of digital computing. Malinowski, B., Alexandrov VA, Boun VP and others/edited by B.N. Malinowski. Kyiv: Tekhnika, 1974), which contains a resistor and reproduces the operation supramed (τ1τ2τ3), where τ1τ2τ3is the duration of the positive pulse signals x1x2x3∈{0,1}, synchronize avannah on the leading edge. For the reason that impede the achievement of specified following technical result when using the prototype include limited functionality due to the fact that no Pets processing seven pulse signals. The technical result of the invention is the extension of functionality by providing playback operation supramed (τ1,...,τ7), where τ1,...,τ7is the duration of the positive pulse signals x1,...,x7∈{0,1}, synchronized on the leading edge. This technical result in the implementation of the invention is achieved in that in the pulse selector containing a resistor, the peculiarity lies in the fact that it introduced the twenty-four keys, which are grouped into six groups so that the first i-I Figure 1 presents the scheme of the proposed pulse selector. Figure 2 shows the timing chart explaining how it works. Pulse selector contains a resistor 1 and wadati four key 2 11,...,262, which are grouped into six groups so that the first i-I The work of the proposed pulse selector is as follows. On his first, ..., seventh inputs are given correspondingly synchronized on the leading edge of a positive pulse signals x1...x7∈{0,1}, with duration τ1,...,τ7respectively. If the control input of all the keys of an arbitrary group applies a logical "1" or a logical "0", then each even-numbered key of this group is respectively closed or open, and every odd key respectively open or closed. Thus, the pulse signal at the output of the proposed pulse selector is defined by the expression where ·, ∨, is a symbol of conjunction, disjunction,inversion. According to (1) have Therefore, the selector (1) to reproduce the operation τZ=supramed (τ1,...,τ7(see figure 2). The above data allow us to conclude that the proposed pulse selector has a wider compared to the prototype functionality, as it provides processing seven pulse signals. The pulse selector containing a resistor, characterized in that it introduced the twenty-four keys, which are grouped into six groups so that the first i-I
