Abstract:The advent of cheap and fast digital integrated circuits permits, at least in principle, the application of digital processing directly to PCM coded telephone signals. At present, the following applications look most promising: channel filters; digital conference circuits; receivers for MFC or touch-tone signals; and sampling rate conversion. Following a review of these fields, an account is given of the problems which exist specifically in a PCM telephone system.
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.
