The PDM signal energy detection circuit also includes a comparator circuit for receiving the analog output signal from the digital-to-analog converter circuit and producing a pulsed signal when a magnitude of the analog output signal exceeds a pre-set threshold. The PDM signal energy detection circuit also has a counter circuit for receiving the pulsed signal from the comparator circuit and producing an energy detection signal when a number of consecutive pulsed signals exceed a pre-set count."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of an acoustic energy detection circuit for a pulse density modulation microphone","description":"A PDM (pulse density modulation) signal energy detection circuit includes a digital-to-analog converter circuit for receiving a PDM digital input signal and producing an analog output signal based on ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10484005","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.
