One Method for Design of Wide-band FIR Filters Without Multipliers

This paper presents the method for the wide-band FIR filters design without multipliers. The proposed method is based on the masking method and the techniques for rounding and sharpening. The coefficient values of the model and masking filters are represented as integers using the rounding technique. The sharpening technique is applied to the masking filters to improve the overall magnitude characteristic and to satisfy the given specification.
