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 eight relators P 1₁-1₈ (dwg.1), each one of which contains comparator 2, connected by its output to first input of XOR element 3, second input of which is relator control input f, while output is connected to controlling input of closing and opening keys 4₁,4₂, outputs of which are combined and form the output of relator together, first and second inputs of which are inputs K 2, connected respectively to inputs of keys 4₁,4₂. Rank filter (dwg.1) by means of two control signals f₁,f₂ realizes selection of minimal, super-minimal, sub-maximal or maximal one of four input analog signals x₁-x₄ and has decreased hardware resource costs when compared to the prototype.

EFFECT: decreased hardware resource costs with preservation of functional capabilities of the prototype.
