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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bi-directional in-line active audio filter","description":"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 ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9711163","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
