This paper presents a prototype system used to detect and compress disturbances commonly found in electrical signal, on both voltage and current. The algorithm for detecting and compressing the disturbances are synthesized in FPGA platform. The compression algorithm operates in three different stages: the innovation stage, the wavelet stage and the bit compression stage. These three stages provide efficient compression rate. Beside the algorithm description, the paper presents details of the hardware implementation and results obtained from synthetized and real signals.
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.
