Abstract
An audio filter for a breathing apparatus uses active filtering in a multi-wire system where one or more electrical conductors contain bi-directional signals using multiple stages of active isolation to separate direct current (DC) power, which is then used to bias an active filtering element. Using active signal conditioning or processing elements, the audio filter directionally separates the power and audio components to allow active conditioning or processing of the audio signal.
