In the process, there is a switch between the different outputs of the amplifier at predefined switching points in time, and the reference voltage of the A/D converter varies over time between the switching points in time in such a way that the echo signal is present at the output of the A/D converter with a transit time-dependent total gain having a predefined characteristic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for amplifying an echo signal suitable for vehicle surroundings detection and device for carrying out the method","description":"A method for amplifying an echo signal, in which an analog echo signal suitable for detection of a vehicle's surroundings is amplified by a gain dependent on the transit time of the echo signal, the a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9698802","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.
