Abstract:
An ultra high speed data encoding apparatus for compressing a sampled ultra high speed data signal having at least one block of signal samples, each signal sample having a corresponding amplitude and each block having at least one peak amplitude value, and each of the signal samples has a sample value corresponding to one level of a corresponding set of first quantizer levels, the apparatus comprising:means for receiving the at least one block of data signal samples; calculating means for calculating a gain value which is proportional to the peak amplitude value from the block of samples; quantizing selection means for selecting a new set of quantizer levels corresponding to the gain value of the block of samples; and quantizer level mapping means for mapping the signal sample value to a compressed level value for each signal sample value of the block of signal samples based upon a relationship between the set of first quantizer levels and the new set of quantizer levels values to choose the compressed level value.
