Abstract

This paper presents a prototype system for detecting and compressing disturbances commonly found in electrical signals, in both voltage and current. The detection and compression algorithms are implemented on an FPGA platform. The compression process operates in three stages: the innovation stage, the wavelet stage, and the bit compression stage, which together provide an efficient compression rate. In addition to describing the algorithm, the paper presents details of the hardware implementation and results obtained from both synthesized and real signals.
