模拟/数字信号转换器 DAC
一个或多个数字信号处理器(DSP)耦合起来可以构成速度很快的模拟-数字转换器(asc)，用来执行信号获取、预处理、触发器生成等操作。
One or more digital signal processors (DSPs) coupled to fast analog-digital converters (ADCs) perform the signal acquisition and pre-processing, trigger generation, and so forth.

A digital-to-analog converter (DAC) for converting a digital signal to an analog signal includes a first thermometer decoder and a second thermometer decoder.
在需要回放时，再由单片机控制提取RAM中的数据，通过D/A转换器将数字信号转换为模拟信号，通过功率放大器将语音信号还原后回放出来。
When this system needs to playback, data is gotten from RAM, and it transforms into the analog signal through the D/A switch. Moreover through the power amplifier, the voice signal can be recovered.
