| Abstract: | 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. |
