Abstract

Level-crossing analog-to-digital converters (LC ADC) have been studied in the literature and have been shown to efficiently sample certain classes of signals. In this paper we first characterize a class of bursty source signals. We then provide an information theoretical formulation that studies the application of LC ADC in data transmission in conjunction with compression. It is shown that compared to uniform sampling, LC sampling enables the same amount of information to be transmitted at substantially lower rate.
