ABSTRACT:
Apparatus and method for data compression in which a coded message representing a digital bit stream is transmitted over a low bandwidth transmission link and received by apparatus which includes a calculator operable to create a sequence of output values comprising the calculated result of a generator equation. The output values comprising a digital bit stream may be converted to analogue form by a digital to analogue converter. By clocking the output of the waveform generating apparatus asynchronously, with respect to its inputs, a high level of data compression occurs.
