Abstract:
A system includes a filter circuit configured to adjust digitized audio signal values based on filter parameters. The system also includes a filter parameter selection circuit configured to determine an audio signal bandwidth estimate based on back-EMF analysis and to supply different sets of filter parameters to the filter circuit based on the audio signal bandwidth estimate and a predetermined threshold. The system also includes a digital-to-analog converter (DAC) configured to convert an output of the filter circuit into an analog audio signal to be amplified.

Claim (Index 9):
The system of  claim 1 , further comprising:\n a voltage sensor configured to obtain voltage measurements associated with a speaker; and a current sensor configured to obtain current measurements associated with the speaker, wherein the filter parameter selection circuit performs the back-EMF analysis based on the obtained voltage measurements and current measurements.
