Multiplier-Free Wide-Band FIR Filter Design Using Modified Frequency Masking Technique

This paper presents a 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 improve the overall magnitude characteristic and to satisfy the given specification.
