摘要
将传输在电话线上的模拟语音信号转化为数字信号,就可以方便地检测、回放、存储、传输语音以满足一些特殊需要。针对这个需求,采用ARM9系列芯片基于嵌入式Linux操作系统设计并实现了该嵌入式设备,经测试达到了各项性能要求,有着广泛的应用前景。
When convert the anolog voice signals into digital signals, it will be convenient to detect, replay, store and translate voices to meet some special requirements. In this paper, we design and implement an embedded device based on ARM9 chips and linux OS. Our experimental results illustrate that the device has high performance which satisfies several requests, thus it can be widely applied.
