dc.description.abstractThe frequency response of conventional FIR digital differentiators (DD), using only integral delays, is poor towards the high frequency end, and becomes identically zero at w=π. To overcome this problem, a half-sample delay, z-1/2, is used in the minimax relative error DDs. However, the order of such DDs grows exponentially when accuracies better than 99.0% are desired. The authors propose maximally linear DDs, using one half-sample delay, which can achieve a frequency response accuracy better than 99.9%, with attractively low orders for 0.5π⩽w⩽π. Mathematical formulas have been derived for computing the coefficients for the designen
