Claim 9:
10. The system according to claim 8, wherein the noise cancellation engine further comprises:
a number (s1+s2) of first interpolators, each performing interpolation over values of multiple first sample points in a first sequence derived from a corresponding microphone and related to a second sampling clock to generate a value of a second sample point in a second sequence related to the first sampling clock, wherein the multiple first sample points are related to the second sample point in time axis;
a second ANC circuitry for performing operations over a number (s1+s2) of second sequences to generate a number U of third sequences; and
a number U of second interpolators, each performing interpolation over values of multiple third sample points in a corresponding third sequence according to the first sampling clock to generate a value of a fourth sample point in a fourth sequence related to the second sampling clock, wherein the multiple third sample points are related to the fourth sample point in time axis;
wherein a frequency of the second sampling clock is related to a fixed time.
