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 filters the vibration signal to remove a noise portion and obtain a processed microphone signal. The processor outputs the processed microphone signal.
