RANK FILTER Russian patent published in 2006 - IPC H03H17/02 H03K5/24 G06G7/52 

FIELD: automatics and analog computer engineering, possible use for building functional nodes of analog computers, means of automatic adjustment and control, analog processors, etc.

SUBSTANCE: rank filter contains five relators P 1₁-1₅ (dwg.1), third-fifth of which contain comparator 2, connected by output to first input of XOR element 4, second input of which is control input P (f), and output is connected to controlling input of keys (3₁, 3₂), outputs of which are combined and form output P, first and second inputs of which are inputs K 2, connected respectively to inputs of keys 3₁, 3₂. First and second relators contain inputs K 2 and additional keys 3₃,3₄, outputs of which are additional output of relator P. Rank filter (dwg.1) by means of two controlling signals f₁,f₂ realizes selection of minimal, super-minimal, sub-maximal or maximal one of four input analog signals x₁-x₄ and has structure, simpler compared to that of the prototype, due to decreased number of controlling inputs.

EFFECT: simplified structure due to decreased amount of controlling inputs.
