摘要

PROBLEM TO BE SOLVED: To obtain an efficient compressing function even for a signal having a wide dynamic range. SOLUTION: This encoding device has an envelope generating means (2) of generating an envelope of an input signal and an encoding means (4) of encoding the input signal with a necessary number of bits at respective points of the envelope.
