| Abstract: | This paper develops a voice compress algorithm-SB-ADPCM (Sub Band-adaptive Differential Pulse Code Modulation). And the problems are discussed about coding , decoding , sending and receiving QMF, adaptive quantization and reconstructed singnal. The intelligent digital recording system with this method is widely used in dispatch of power. |
