摘要
在高密度可编程逻辑器件上设计电路,实现语音信号的压缩编码,即线性脉冲编码调制(PCM)码转换成A律PCM码。通过仔细分析A律PCM码的特点,使得整个电路占用了很少的逻辑单元,提高了集成度。
A circuit is designed on high-density-programmable-devices, which is used for compression coding of speech signals,namely the conversion from Pulse-Code-Modulation code to A-law PCM code. By careful analysis of the characters of A-law PCM code, fewer logic cells are used for the whole circuit, and the density of integration is improved greatly.
