Abstract
An integrated circuit includes a processor that upsamples a vibration signal. The processor determines a correlation value. The correlation value may be based on a microphone signal, the upsampled vibration signal, or both. The processor determines filter coefficients. The filter coefficients may be determined based on the correlation value being above a threshold. The filter coefficient may be based on the upsampled vibration signal. The processor filters the vibration signal based on the filter coefficients to remove a noise portion and obtain a processed microphone signal. The processor outputs the processed microphone signal.
