Abstract:
A noise cancellation system, comprising: an input for a digital signal, the digital signal having a first sample rate; a digital filter, connected to the input to receive the digital signal; a decimator, connected to the input to receive the digital signal and to generate a decimated signal at a second sample rate lower than the first sample rate; and a processor. The processor comprises: an emulation of the digital filter, connected to receive the decimated signal and to generate an emulated filter output; and a control circuit, for generating a control signal on the basis of the emulated filter output. The control signal is applied to the digital filter to control a filter characteristic thereof.

Claim (Index 15):
A mobile device, comprising:\n a connection socket for an accessory, wherein the accessory comprises a reference microphone configured to produce a reference microphone signal in response to a first acoustic signal; and an error microphone configured to produce an error microphone signal in response to a second acoustic signal; a first analog-to-digital converter (ADC) that is coupled to the reference microphone when the accessory is connected to the connection socket, and is configured to produce an output signal that is based on the reference microphone signal; a second ADC that is coupled to the error microphone when the accessory is connected to the connection socket, and is configured to produce an output signal that is based on the error microphone signal; a processor having a first input coupled to the first ADC, a second input coupled to the second ADC, and a third input configured to receive a desired sound signal at a first sampling rate and configured to provide updates based on the first, second, and third inputs; and a digital filter that is coupled to the first ADC, arranged to receive the updates from the processor, and configured to filter a reference noise signal that is based on the output signal of the first ADC, at a second sampling rate that is higher than the first sampling rate, to produce an anti-noise signal.
