The main specifications -power intrinsic noise and noise power undercompensation.The comparison of the specifications developed by the echo canceller with the characteristics of the classical echo canceller Widrow.Index Terms -invariant, echo canceller, stability.
The summary -the analysis of qualitative parameters of invariant system is made at a noncorrelation of counting of noise and existence of a selective fading. The probability of paired transition of invariants is calculated. The structure of invariant system is offered.
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.
