Claim 29:
30. The method according to claim 28, wherein the step of generating the number U of anti-noise signals further comprises:
performing interpolation over values of multiple first sample points in each of first sequences derived from the reference and the error microphones 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;
performing ANC operations over a number (s1+s2) of second sequences to generate a number U of third sequences;
performing interpolation over values of multiple third sample points in each 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.
