<p>The present invention is involves a High Speed Data encoding apparatus for compressing a sampled data signal having at least one data signal block of samples comprising: means for receiving the at least one data signal block which contains at least one data signal sample having at least one peak amplitude value; calculating means for calculating a respective gain value for each data signal block, the gain value proportional to the peak amplitude value; and selecting means for selecting a uniform quantizer corresponding to the gain value, the uniform quantizer having a plurality of uniformly spaced quantizing level values which are determined from the gain value; €ƒ€ƒ€ƒ
wherein the selected uniform quantizer quantizes each data sample of the data signal block, and provides a plurality of compressed data samples.</p> |
