1. A method comprising:

  • sampling an analog waveform and converting the waveform into a digitized data set;

    generating an encoded waveform data point for each of an equivalent data point from a subset of the digitized data with a predictive encoding process; and

    substituting a codeword for an encoded waveform data point using an entropy encoding process if a predetermined condition is met, wherein the codeword is stored into a memory when the predetermined condition is met or the encoded waveform data point is stored into the memory when the predetermined condition is not met.
