ABSTRACT:
Input data, distributed along a time axis, is converted into data distributed along a frequency axis by the use of a frequency range dividing filter, and is subjected to scalar quantization performed by a compression circuit with different step numbers for different frequency ranges, so that data in a plurality of frequency ranges along the frequency axis is compressed.
