METHODS AND SYSTEMS FOR DETECTING AND MANAGING UNEXPECTED SPECTRAL CONTENT IN AN AMPLIFIER SYSTEM

A method may include receiving, by a transducer driving system, a first signal for driving an amplifier that drives an electromagnetic load and receiving, by the transducer driving system, a second signal driven by the amplifier in order to control a feedback loop of the transducer driving system.

Zusammenfassung:A method may include receiving, by a transducer driving system, a first signal for driving an amplifier that drives an electromagnetic load and receiving, by the transducer driving system, a second signal driven by the amplifier in order to control a feedback loop of the transducer driving system. The method may also include detecting unexpected spectral content in the second signal, declaring an indicator event based on the detected unexpected spectral content, determining whether the indicator event occurs in an undesired pattern, and in response to the indicator event occurring in the undesired pattern, modifying a behavior of the transducer driving system.
