BIDIRECTIONAL LIMITER Russian patent published in 2002 - IPC

FIELD: automatic control and analog computer engineering. SUBSTANCE: bidirectional limiter that may be used for building functional units of analog computers, automatic monitoring and control facilities, analog processors, and the like has two relators 1₁,1₂ each incorporating comparator 2 whose noninverting and inverting inputs are connected to first and second inputs of relator, respectively; first input of first relator 1₁ is connected to data inputs of bidirectional limiter; newly introduced in each relator are EQUIVALENCE gate 3, making and breaking switches 4₁,4₂ whose outputs and control input are connected to relator input and to gate 3, respectively, first and second inputs of the latter being connected, respectively, to switch output and to relator control input; first and second inputs of relator are connected to inputs of making and breaking switches, respectively; outputs of first and second relators 1₁,1₂ are connected, respectively, to first input of second relator 1₂ and to output of bidirectional limiter. Device provides for reproducing functions of bidirectional limiting levels of analog signal x by reference voltages x₁ and x₂ both at x₁<x₂ and x₁>x₂. EFFECT: enlarged functional capabilities. 3 dwg
