Abstract:We present a fast algorithm for exact extrapolation of a discrete-time and periodic band-limited signal from its values in an interval having the same length as the band-width of the signal. Here band-width is the number of non-zero values in one period of the discrete Fourier transform of the signal. Applications to problems in which the number of given values is unequal to the band-width are also given. The procedure is a simple autoregression on the time-domain values of the signal, and is much simpler than… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
