Abstract :
The classical “frequency sampling method” (1975) based on the direct utilization of the Lagrange interpolation technique is extended in a natural way to a rather efficient Hermite interpolation scheme. This structure is a new extension related to the resonator-based digital filter family introduced by M. Padmanabhan et al. (1996). The development resulted in a system having good properties if measurement of signals consisting of sinusoidal components is to be performed
