Abstract

This paper presents a reconstruction technique based on zero-crossing detection that permits analyzing FM-modulated signals using digital ATE channels. The technique relies on sampling of the analog/RF signal through a 1-bit comparator and the post-processing of the resulting bit stream. The proposed solution is validated through both simulation and hardware experiments.
