We develop a new design method of FIR filters with steep cut-off, using a series connection of multiplicaion-summation modules of scaled versions of basic filters. The module turns out to correspond to the recursion of so-called mean operation, in principle. Numerical example shows the proposed method outperforms conventional method in both steepness and number of multipliers.
