Abstract
A fluidic circuit (10) having two oscillators (22,24) which separately vent to a common volume (78) and receive pressurized fluid inputs along separate flow paths (54,56) is provided with filters (80) positioned both upstream and downstream from each oscillator. Each of the filters (80) is adapted to attenuate oscillator-induced noise and comprises a series combination of an inductive element (82), a capacitive element (84), and an inductive element (86).
