1. a filtering method, is characterized in that, described method comprises:

  • Receive pending sampled signal;

    By the N group operator each self-corresponding Branch Computed pre-set, convolutional calculation is carried out to described sampled signal, described N group operator is obtain by cutting successively the filter operator of finite length, the length often organizing operator meet 2 power side and power be more than or equal to 1 positive integer, N >

    =2;

    The result of calculation of each self-corresponding Branch Computed of described N group operator is merged;

    Result of calculation after merging is exported as the result to described sampled signal.
