The invention relates to the pulse technique and can be used for building automation, functional units of control systems and others
Known pulse selectors (see, for example, is on str in the book of Digital and analog integrated circuits: the manual / SV Yakubovsky, LI, Nisselson, I. Kuleshova and others; edited by S.V. Yakubovsky. - M: Radio and communication, 1989), each of which has an exit and plays operation med(t 1 ,t 2 ,t 3 ), where t 1 ,t 2 ,t 3 has a duration of three positive pulse signals synchronized on the leading edge.
The reason that impede the achievement of the specified below a technical result, when using known pulse selectors are limited functionality, due to the fact that not admitted to treat five pulse signals.
The closest device to the same destination to the claimed invention by a combination of traits is adopted as a prototype pulse selector switch (figure 1, page 9 in the book Charaev - Technical diagnostics of digital devices integral electronics. - M: Energiya, 1974), which has an exit and plays operation med(t 1 ,t 2 ,t 3 ), where t 1 ,t 2 ,t 3 is the duration of the positive pulse signals x 1 ,x 2 ,x 3 belongs to{0,1}synchronized on the leading edge.
The reason that impede the achievement of the specified below a technical result, when using the prototype, are limited functionality, due to the fact that not admitted to treat five pulse signals.
The technical result of the invention consists in expanding the functional possibilities by ensuring playback operations med(t 1 ,...,t 5 )where t 1 ,...,t 5 is the duration of the positive pulse signals x 1 ,...,x 5 belongs to{0,1}synchronized on the leading edge.
This technical result by carrying out the invention is attained by the fact that in pulse the selector containing the output, the peculiarity lies in the fact that it introduced a resistor and fourteen keys, which are grouped into four groups so that the first, second, third and fourth groups contain respectively three, five, four and two keys, with even and odd keys educated groups are made accordingly tripping and closing, in each group, the output of the previous odd key connected to the output of the next key in every group except the fourth entrance previous even key is connected to the input of the following key outputs of the first, third and inputs of the first, third, fourth keys of the third group are connected, respectively, to the input of the first, second key fourth group and outputs of the first, third and fifth keys of the second group, the connected inputs respectively to the bus singular potential, the outputs of the first third of the keys of the first group, the inlets of which are connected respectively with bus singular potential, fifth channel pulse selector, the i-th input and output of which is connected respectively with the managing all of the i-th group and the release of the first key of the fourth group, connected through a resistor to the bus zero potential.
Figure 1 shows the scheme of impulsive selector. Figure 2 shows the timing diagram explaining how it works.
Pulse selector contains a resistor of 1 and fourteen 2 keys 11 ,...,2 42 , which are grouped into four groups so that the first, second, third and fourth groups contain respectively three key 2 11 , 2 12 , 2 13 , five keys 2 21 , 2 22 , 2 23 , 2 24 , 2 25 , four keys 2 31 , 2 32 , 2 33 , 2 34 and two keys 2 41 , 2 42 , with even and odd keys educated groups are made accordingly tripping and closing, in each group exit previous odd key connected to the output of the next key in every group except the fourth entrance previous even key is connected to the input of the following key outputs key 2 31 , 2 33 and inputs keys 2 31 , 2 33 , 2 34 is connected respectively with the inputs of the keys 2 41 , 2 42 and outputs of the keys 2 to 21 2 23 , 2 25 , connected inputs respectively to the bus singular potential, the outputs of the keys 2 to 11 , 2 13 , the inlets of which are connected respectively with bus singular potential, fifth channel pulse selector, the i-th input and the output of which is connected respectively with the managing entrance all of the i-th group and access key 2 41 , connected through a resistor of 1 to the bus zero potential.
The work proposed pulse selector as follows. At its first, ..., fifth inputs are served respectively synchronized on the leading edge positive impulse signals x 1 ,...,x 5 belongs to{0,1}, with duration t 1 ,...,t 5 respectively. If the control input of all the keys of an arbitrary group operates a logical "1" or a logical "0", then every odd key of this group, respectively closed or open, and every even key respectively is open or closed. Thus, the pulse output pulse offer selector is determined by the expression
where ·, ∨, - is a symbol of conjunction, disjunction, inversion. Consequently, the selector switch (figure 1) will play the operation t Z =med(t 1 ,...,t 5 ) (see figure 2).
The above data allow us to conclude that the proposed pulse selector has a wider in comparison with the prototype functionality, as it provides the processing of the five pulse signals.
