Abstract

FIELD: radio engineering, communication.

SUBSTANCE: rank filter is intended for the rank processing of analogue signals and can be used in analogue computational systems as a data preprocessing facility. Each of the ten relators (11,…,110) of the rank filter contains a comparator unit (2), EXCLUSIVE OR element (3), closing and opening keys (41 and 42).

EFFECT: functionality expansion owing to the implementation of selecting of minimum, supraminimum, submaximum or maximum out of five analogue input signals.

Description

The invention relates to automation and analog computing and can be used to build functional units of analog computers, means of automatic regulation and control, analog processors, etc.

Known rank filters (see, for example, figure 1 in the description of the invention to the patent of the Russian Federation 2284652, CL G06G 7/52, 2006), which contain relators and implement the choice of the minimum, supraminimum, submaximal or maximum of the four input analog signals .

The reason that impedes the achievement of the technical result indicated below when using known rank filters includes limited functionality due to the fact that five input analog signals are not allowed to be processed.

The closest device of the same purpose to the claimed invention in terms of features is the rank filter adopted for the prototype (Fig. 1 in the description of the invention to RF patent 2284650, class G06G 7/52, 2006), which contains relators and implements the choice of the minimum supraminimum, submaximal, or maximum of four analog input signals.

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 five input analog signals.

The technical result of the invention is the expansion of functionality by providing the implementation of the choice of the minimum, supraminimum, submaximal or maximum of the five input analog signals.

The work of the proposed rank filter is as follows. At its first, ..., fifth information inputs, respectively, the analog signals (voltages) x ₁ , ..., x ₅ to be processed are fed; the necessary control signals ƒ ₁ , and ƒ ₂ , ƒ ₁ , ƒ ₂ ∈ {0,1} are respectively fixed on its first and second control inputs. If at the control input of the relator there is a logical “0” (logical “1”) and the signal at its first input is more or less than the signal at its second input, then key 4 _{1 is} respectively closed (open) or open (closed), and key 4 ₂ respectively open (closed) or closed (open). Therefore, if at the control input of the relator there is a logical “0” (logical “1”), then this relator will select at its output the largest (smallest) of the signals acting on its first and second inputs. Thus, the operation reproduced by the proposed filter is determined by the expression

The above information allows us to conclude that the ranking filter (figure 1) has a wider functionality compared to the prototype, as it implements the choice of the minimum, supraminimum, submaximal or maximum of five input analog signals.
