Nonuniform sampling and reconstruction of waveforms and its extension to wide band signal

In this paper nonuniform sampling has been used to develop an efficient and adaptive recorder for wide band signals. Previously established theoretical results have been successfully utilized to produce a practically implementable sampling system. Two important application areas e.g. power system fault. Recording and double exponential waveform recording, have been considered with a considerable amount of improvement over presently used uniform sampling systems. The algorithms have been implemented in C and ASSEMBLY level programming. A PC-based system has been developed with a 1:15 sampling rate variation which will be useful for power system fault recorder
