In addition, an autocorrelation function is performed on the received signal to discriminate between the set up signal and other signals in the received signal and a check signal is provided when the autocorrelation function identifies the set up signal. The set up signal in the received signal is detected in response to the first and the second detect signals and the check signal. A method of detecting phase reversals in the set up signal is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for detecting a set up signal used for data communication over a communication network","description":"A method of detecting a set up signal having a predetermined frequency and used for data transmissions over a communication network comprises comparing an energy level of a filtered received signal wi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9674070","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.
