Abstract : Three data compression systems were analyzed and compared in terms of their bit rate and sampling error. The quantization error was not included in the system analyses since it was the same for all the systems due to the type of signals considered. The conventional data system was included as a comparison for the compression systems. The non-uniform sampling system was shown to be an ideal system with no error. The rate of this system is the lowest rate required to achieve no sampling error. The sample elimination method, a redundancy reduction system, was compared to the quantization of amplitude and time system, a form of run-length encoding. The analyses presented are an attempt to further the study of data compression techniques. Other work needed in this area includes computing error curves to facilitate selecting an optimum bit rate with minimum error. (Author)
