¿µ¹®³»¿ë¿ä¾à The main parts of this standard describe a general outline of the G.711.1 algorithm, the G.711.1 encoder and decoder principles, and presents the transmitted parameters. And the software that defines this coder in 16-32 bit fixed-point arithmetic is described. Appendix I provides a supplemental functionality enhancing the quality of the decoded signal when a legacy G.711 or only the basic log companded PCM part is available.
