ABSTRACT:
A fluidic complementary gain changing circuit has three laminar proportio amplifiers, one of which supplies fluid pressure streams to the other two. The latter amplifiers have substantially identical geometries and complementary gain curves at any given supply pressure, relative to a gain changing signal constituting a bias pressure applied to control ports of the first amplifier. A differential input signal supplied to the control ports of the two complementary amplifiers modulates the supply streams traversing those amplifiers and results in concurrent high and low gain complementary signals at the respective outlet ports of the overall circuit. Variable resistance elements permit calibration of the circuit.
