Abstract
A method of compressing a digitized waveform into a sequence of N-bit words includes selecting corresponding bit values from N data words and generating a value based thereon. A next N input words are selected and the corresponding bits are used to generate a next value. The process is continued for each significant bit of the input sequence and the generated value stream is run-length encoded to produce a compressed data output stream.
