Tallinn: Academy of Sciences of Estonia, 1991) that identify the supraminimum value of an information analog signal .

The reason that impedes the achievement of the technical result indicated below when using known logical devices is limited functionality, due to the fact that a device circuit configuration is required to configure the identification of the submaximal value of the information signal.

The definition from the list of identified analogues of the prototype, as the closest in terms of the set of essential features of the analogue, allowed to identify the set of significant distinguishing features in relation to the technical result perceived by the applicant in the claimed device set forth in the utility model formula. Therefore, the claimed utility model meets the condition of novelty.

Figure 1 presents a diagram of the proposed logical device. In Fig.2 shows a diagram of single-key (Fig.2A) and three-key (Fig.2B) relators that are used in the proposed device.

Each relator contains a comparator 2, connected by an output to the first input of the logic element 3, reproducing the operation "Equivalence, the second input of which is the relay control input, and the output is connected to the control input of the closing key 4i in the single-key relay (Fig. 2a) or to the control input of the first the key 4i made closing, the second key 42 made disconnecting, and the third key 4z made closing, in the three-key relay (Fig.26). The non-inverting comparator inputs of the relators 1, ..., „are the inputs of the corresponding driving voltages, their inverting comparator inputs are combined and form the information input of the logic device, the identifying input of which is connected to the relay switching input li and to the first switching relay input b, the relay output li is connected with the second and third switching inputs of the relator b, the first and second outputs of the relator 1,

With / 1 (/ 6 {0, l | -signal at the control input of the logic device) and or with / О and л, jc

the closing keys 41.4z are closed, the opening key 42 is open, and with / О and л :,; with or with / 1 and jc, l: we have the opposite picture, that is, the signal / changes the switching logic of the relay inputs of relays. In the prototype, a similar change is achieved by rebuilding its circuit (by replacing the closing and opening keys, respectively, with the opening and closing keys or by interchanging the comparator inputs of the relators). Thus, the operation reproduced by the proposed logical device is defined by the expression:

I y for X e O for X

where the superscript, Г2 (, 2 2 at / 1; Г and +1, 2 and at / 0) is the rank (serial number) of the information signal x in the sequence x ... obtained by ranking the signals Xi ,, .., x , x in ascending order.
