发明名称 A loudspeaker drive circuit for determining loudspeaker characteristics and/or diagnostics
摘要 A loudspeaker amplifier drive circuit performs analysis of various signals relating to the input and output of the amplifier such that the characteristics and/or diagnostics of a loudspeaker driven by the amplifier can be derived. These are then presented as outputs, so that different circuitry can make use of the information for audio signal processing.
