The FSK demodulator also includes a result combining stage configured to output a set of first correlation results based on correlation metrics generated for a first portion of the input signal encoding a current symbol and at least one past symbol, and a set of second correlation results based on correlation metrics generated for a second portion of the input signal encoding the current symbol and at least one next symbol; and a time combining stage configured to combine a set of delayed first correlation results with the set of second correlation results to produce a demodulation decision that returns a most likely symbol value for the current symbol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency shift keying (FSK) demodulator and method therefor","description":"A frequency shift keying (FSK) demodulator for demodulating symbols includes correlation circuits configured to output correlation metrics based on a buffered portion of an input signal as the input s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9729364","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.
