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 seven relators P 1₁-1₇ (dwg.1), each one of which contains comparator 2, connected by output to first input of XOR element 3, second input of which is input for controlling adder frequency, while output is connected to controlling input of closing and opening keys 4₁,4₂, outputs of which are combined and form output of relator, first and second inputs of which are, respectively, inputs K 2, connected appropriately to inputs of keys 4₁,4₂. 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 higher speed of operation compared to prototype.

EFFECT: increased speed of operation with preservation of functional capabilities of prototype.
