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, Fig. 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 n = 4 input analog signals. At the same time, the number of hardware relators, in particular, the aforementioned analogue, is 3 × n-5.

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 six 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 the patent of the Russian Federation 2543307, class G06G 7/52, 2015), which contains relators and implements the choice of the minimum, supraminimum, submaximal or maximum of n = 5 analog input signals. In this case, the number of releasers of the hardware composition of the prototype is 3 × n-5.

Each relator contains a comparator 2 connected by the output to the first input of the element exclusive OR 3, the second input of which is the input of the relay control, and the output is connected to the control input of the closing and disconnecting keys 4 ₁ and 4 ₂ , the outputs of which are combined to form the output of the relay, the first and the second inputs of which are respectively the non-inverting and inverting inputs of the comparator 2, connected respectively to the inputs of the keys 4 ₁ and 4 ₂ .

The work of the proposed rank filter is as follows. The necessary control signals f ₁ , 1 ₂ ∈ {0,1} are respectively fixed on its first and second control inputs. At the first and second inputs of the relators 1 ₁ , 1 ₁₀ ; the first and second inputs of the relators 1 ₆ , 1 ₁₁ ; first and second inputs relators 1 _8, 1 ₁₃ applies accordingly be processed analog signals (voltage) x ₁ and x _2; x ₃ and x ₄ ; x ₅ and x ₆ . 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, at the output of the proposed filter we get

where the symbols ∨ and · denote the operations max and min, respectively.

The above information allows us to conclude that the rank filter (Fig. 1) has a wider functionality compared to the prototype, as it implements the choice of the minimum, supraminimum, submaximal, or maximum of n = 6 input analog signals. In this case, the number of releasers of the hardware composition of the specified filter is 3 × n-5.
