In this paper FIR filter is designed by two algorithms. We consider the filter order and sparsity of filter to implement the FIR Filter. The problem identification handles by the l0-norm minimization which can be implemented by two different algorithms. In first design approach the upper bound value taken into consideration which leads to weighted l 0 -norm minimization problem, in the second one a problem transformed into another weighted l 0 -norm minimization. Weighted l 0 -norm minimization problem can be tackled by the IRLS algorithm to solve the problem. Both Sparsity and filter order design approach provides the best FIR Filter Design. From this reduced coefficient set, we can implement multiplierless FIR filter to achieve the reduced hardware design.
