Analog signal digitization/data compression involves carrying out multi-dimensional spherical logarithmic quantization of analog source signal, transformation of source signal in spherical coordinate

摘要

The digitization and data compression method involves carrying out a D-dimensional spherical logarithmic quantization of the analog source signal. It involves carrying out a transformation of the source signal in spherical coordinates. A logarithmic quantization of the magnitude or a non-uniform quantization of the angle coordinates is carried out in spherical coordinates. An independent claim is also included for the following: (A) an arrangement for compression of analog signals.
