Remarkable improvement in the performance of digitally handled systems may be achieved by using properly adjusted fractional-order hold (FROH) circuits. Nevertheless, the tuning methods formerly proposed in the bibliography are exclusively applicable for a certain range of sufficiently small sampling periods. Such a range is analytically obtained and its significance for the applicability of such methods is discussed.
