Abstract :
Level-crossing A/D converters (LCA/D) have been considered in the literature and have been shown to efficiently sample certain classes of signals. In this paper we provide a stable algorithm to perfectly reconstruct signals of finite rate of innovation using level-crossing samples. Furthermore, we also apply level-crossing sampling to detection of event-arrival signals.
