This study contributes to advancing synchronized phasor measurement theory to improve the reliability and engineering performance of protective relaying, automation, control, and monitoring systems. The focus is placed on enhancing current synchrophasor estimation algorithms that utilize Rogowski coils as primary transducers. We propose the use of averaging finite impulse response filters with a complex-valued impulse response to augment the accuracy and computational efficiency of current synchrophasor estimation. The findings on the synthesis of these filters are presented
