ABSTRACT:
A second evaluation value calculation circuit calculates an evaluation value from a first linear prediction coefficient, a second linear prediction coefficient stored and held, a third linear prediction coefficient read from a table in which a plurality of linear prediction coefficients are stored in advance, and a fourth linear prediction coefficient selected, stored and held among the third linear prediction coefficients read from the table in the past, while a second evaluation value minimizing circuit selects the third linear prediction coefficient with which the evaluation value is the minimum and outputs a code corresponding to the selected third linear prediction coefficient as a code decodable by a second coding and decoding system.
