1. A method using a computer for converting a string of binary bits of indefinite length into compressed impulse format, said method comprising the steps of:

  • grouping the successive bits of said string into a corresponding sequence of one or more uncompressed impulses which together constitute substantially the entire bit string, each said one or more impulses comprising a run of one or more contiguous bits of said string having the same polarity followed by the next bit of said string having a polarity opposite from said same polarity of the associated impulse; and

    encoding each said one or more uncompressed impulses in sequence into a corresponding sequence of compressed impulse formats, one compressed format for each and every uncompressed impulse, said compressed impulse format comprising first and second binary bit coded indicators, said first indicator indicating the polarity of said one or more same polarity bits of the corresponding uncompressed impulse and said second indicator indicating the quantity of said same polarity bits grouped in the corresponding uncompressed impulse.
