For computing characteristic parameter of a FIR filter, the authors adopt a method to construct function of frequency spectrum. The method is relatively high in performance and simple in operation, as compared with common algorithm. Its design parameters have passed through software program verification and hardware measurement. This algorithm is indicated by results to be correct and reliable, it fulfils the requirement of design.
