The selected portions are then averaged and another cross correlation is performed between the quasi-periodic signal and a template including the averaged selected portions. The instantaneous period is then measured from the correlation signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for measuring the instantaneous period of a quasi-periodic signal","description":"A method of measuring the instantaneous period of a quasi-periodic signal includes determining an initial template, performing a cross-correlation between the initial template and a quasi-periodic sig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8491481","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.
