Abstract:
A method for determining the presence of unwanted signal components in an acoustic signal, comprises: receiving a first microphone signal derived from an acoustic signal, applying the first microphone signal to a first signal processing path having a first transfer function to provide a first output, receiving a second microphone signal derived from the acoustic signal, applying the second microphone signal to a second signal processing path having a second transfer function to provide a second output, wherein the second transfer function has a different degree of linearity from the first transfer function, and determining the presence of unwanted signal components in the acoustic signal based on a comparison of the first output and the second output.

Claim (Index 24):
An analog front end, comprising:\n a first signal processing path for receiving a first microphone signal derived from an acoustic signal, wherein the first signal processing path has a first transfer function and provides a first output, a second signal processing path for receiving a second microphone signal derived from the acoustic signal, wherein the second signal processing path has a second transfer function and provides a second output, and a comparator for determining a presence of unwanted signal components in the acoustic signal based on a comparison of the first output and the second output; wherein:\n the first and second signal processing paths are configurable such that the second transfer function has a greater linear range of operation than the first transfer function; and \n configuring the first and second signal processing paths comprises at least one of:\n applying different supply voltages to the first and second signal processing paths; and \n applying a DC offset to one of the first and second signal processing paths.
