An audio circuit (210) has an input node (103) for receiving an input audio signal (SIN) and an output node (104) for outputting an output audio signal (AOUT) for driving an audio load. A monitoring module (202) receives a first signal (S1) derived from the output audio signal and a second signal (S2) indicative of the input audio signal. The monitoring module (202) monitors the first signal (S1) with respect to the second signal (S2) to determine whether at least one parameter of the first signal corresponds to an expected parameter value based on the indication of input audio signal. If the parameter does not correspond to the expected parameter value, the monitoring module (202) outputs an indication (CTRL) of a defective operating state of the audio circuit (201)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio circuitry","description":"This application relates to methods and apparatus for monitoring the operating state of an audio circuit, and in particular for detecting a defective operating state, as may occur after an Electrical ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10506338","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.
