数字模拟转换 digital-analog conversion
- 模拟音乐通过模拟数字转换器转换为数字信号。
Analog music is converted to a digital signal via an analog-to-digital converter. - 数据解码系统需要几个子系统:解调器、误码探测和纠正、信号分离器、和数字模拟转换器。
The data decoding system entails several subsystems: demodulator, error detection and correction (EDC), demultiplexor, and digital-to-analog converters. - 由于数字-模拟转换器会在控制器内产生多余的欧姆热,人们改用脉冲宽度调制来控制平均电流。
As a digital-to-analog converter produces unwanted ohmic heat in the controller, pulse-width modulation is used instead to regulate the mean current.
