N2 - This paper investigates the intrinsic problems of a digital implementation of a ZePoC Codec. We will review the basic steps of a ZePoC modulator, showing its intrinsically analog nature. Then we will evaluate the loss of performance of a digitally implemented ZePoC modulator, in terms of harmonic distortion within a certain low-pass band. To do this, we developed a fully analytical method to evaluate the effects of non linearities over quasi periodic signals. Finally, an application of the analytical method will be shown in an example. The example results will suggest that, though ZePoC modulator is theoretically optimal, its digital implementation would unavoidably lead to a high loss in its performance.
