Md Raju Ali, Jobbin Abraham Ben

Abstract: Based on published Area efficient VLSI implementation for parallel linear phase FIR digital filter of odd length based on fast FIR algorithm, this paper proposes a parallel FIR filter structure with less hardware complexity. In previous paper using carry save adder are replaced by ripple carry adder which can reduce the area.
