A very efficient technique for drastically reducing the number of multipliers and adders in implementing linear-phase finite impulse response filters is to use the frequency-response masking approach. A drawback in the original synthesis technique is that the subfilters in the overall implementation are designed using time-consuming linear programming. In order to get around this problem, this paper shows how these subfilters can be designed by using the Remez algorithm. This makes the overall synthesis dramatically faster for both the one-stage and multistage frequency-response masking approach
