Abstract:The harmonic analysis of binary approximations to trigonometric reference functions employed in digital signal processing functions is described. An analytic representation of the decomposition of sine or cosine functions into elementary rational binary functions is suggested which permits a direct solution to the problem of calculating the harmonics of the error of approximation. For applications, such as ROM based frequency -synthesizers, angle-encoders, and discrete Fourier transformations, the approach ill… 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.
