摘要
分析了自适应差值脉码调制(ADPCM)的原理及其算法,根据CCITT G721建议,采用C语言,对其中的复杂过程进行了模拟。由于这种模拟具有计算精确和图形显示直观等优点,在科研工作和教学实验中均起了一定的作用。
The principles and algorithm of the adaptive differential pulse-coded modulation (ADPCM) are analyzed. A simulation program is written to demonstrate the complicated process of ADPCM. The program, which is written in C language, has the advantages of high precision and vivid graphic display, so it is useful in both research and classroom instruction in the field of digital communications.
