Claim 8:
9. A signal processing method, for generating at least one output according to a plurality of inputs and a plurality of coefficients, comprising:
obtaining a series of inputs and a series of coefficients, wherein the series of inputs comprises the plurality of inputs and the series of coefficients comprises the plurality of coefficients;
adjusting arrangement of the series of inputs or the series of coefficients according to a count value to generate a series of rearranged inputs or a series of rearranged coefficients;
sequentially multiplying the inputs comprised in the series of rearranged inputs by the coefficients comprised in the series of coefficients or sequentially multiplying the inputs comprised in the series of inputs by the coefficients comprised in the series of rearranged coefficients to generate a plurality of multiplication results;
summing up the multiplication results to generate the at least one output; and
storing the inputs in a plurality of registers of a filter circuit;
wherein when the filter circuit receives a new input, the new input is written in the register which stores the oldest input among the inputs currently stored in the registers to replace the oldest input.
