RANK FILTER Russian patent published in 2021 - IPC G06G7/52 

FIELD: computing technology.

SUBSTANCE: invention relates to a rank filter. The filter comprises two sorters and eight relators, wherein each relator comprises a comparator connected by the output thereof to the first input of the exclusive OR element, the second input whereof is the control input of relator and the output is connected with the control input of the connecting and disconnecting keys, the outputs whereof are combined and form the output of the relator, the first and second inputs whereof are the non-inverting and inverting inputs of the comparator, respectively, connected respectively to the inputs of the connecting and disconnecting keys, the "med" output of the first and the "min" output of the second sorters are connected with the first input of the fifth and the second input of the sixth relators, respectively, the outputs of the i^th and sixth relators are connected to the first inputs of the (i+1)^th and seventh relators, respectively, and the control inputs of the first, third, fifth, sixth relators and the i^th input of the k^th sorter are connected with the second control and (i+k2-1)^th information inputs of the rank filter, respectively, according to the invention, the second input of the fifth, the first input of the sixth, and the first, second inputs of the first relators are connected with the "med", "max" outputs of the second and the "max", "min" outputs of first sorters, respectively, the second inputs of the second, third, fourth, seventh and the first input of the eighth relators are connected to the outputs of the sixth, fifth, eighth, first and seventh relators, respectively, and the control inputs of the second, eighth and the output of the fourth relators are connected with the first control input and output of the rank filter, respectively, the second control and the seventh information inputs whereof are connected to the control inputs of the fourth, seventh and the second input of the eighth relators, respectively.

EFFECT: increased operating speed of the rank filter.
