| Abstract: | This article puts forward the idea of applying the CVSD compiling technology to the PCM encoding experimental system which uses the TCM29C14 chip.Without the influence of signal transmitting code error,this technology improves the system's proportion of signals-to-noises ratio when transmitting and accepting signals from one time to more times,thus bringing about better compiling effect in the transmission of speech and sound signals by multi-means. |

| Keywords: | CVSD PCM transfer of encoding number signals-to-noises ratio |
