The inflection point detector includes an inflection point extraction part to extract the inflection point corresponding to variation of a sample value of an amplitude value of the frequency detection signal, an amplitude determination part to determine if a size between peak values of sample values in front and rear of the inflection point exists in a first predetermined range, a preamble determination part to determine if a difference between initial and final sample values of at least one of a symbol having the extracted inflection point and a right before symbol exists in a second predetermined range, and an AND operation part to determine a normal inflection point."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"FSK demodulator","description":"An FSK demodulator and a method for detecting an inflection point extract a greater amount of effective inflection points of a frequency detection signal while reducing erroneous detection of the infl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8519784","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.
