The paper deals with the problem of estimating the influence of truncation error in case of asynchronous sampling of the ac signal in the presence of subharmonics and interharmonics. The analysis makes use of the most general model of the voltage and current signal, i.e. the most complex spectral content that can be expected to appear in practice. In this paper, different processing methods are compared end equations derived for worst-case errors. A simulations and experimental check of the suggested procedure have been done as well. On the base of the derived relation it is possible to select, the best processing method and select the necessary number of samples in case of such a complex signal. The paper investigates the errors related to the proposed processing method, and provides estimation of truncation affect.
