模数转换器(ADC)将模拟量——现实世界中绝大部分现象的特征——转换为数字语言，以 便用于信息处理、计算、数据传输和控制系统。数模转换器(DAC)则用于将发送或存储的 数据，或者数字处理的结果，再转换为现实世界的变量，以便控制、显示信息或进一步进 行模拟处理。(Analog-to-digital converter (ADC) analog- the vast majority of real-world phenomena characteristic- converted into digital language, in order for the information processing, computing, data transmission and control system. A digital-to-analog converter (DAC) is used to transmit or store the data, or the result of the digital processing and then converted to the real world variables, in order to control, displays a message or further subjected to analog processing.)
