The data decoding system entails several subsystems : demodulator , error detection and correction ( edc ) , demultiplexor , and digital - to - analog converters 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 digital upward frequency conversion is the key element of the waveform synthesis . at the same time , basic theoretical analysis and optimum design are done for pci bus slave interface , fifo , transmit signal processor , digital - to - analog converter and logic control 本文对波形合成技术的核心? ?数字上变频进行了深入细致的研究和介绍,同时对波形合成器中的pci总线接口、先进先出缓冲器、发射信号处理、数模转换及逻辑控制等部分进行了分析和优化设计,给出了最佳设计方案。
In electronics, a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary) code to an analog signal (current, voltage, or electric charge). An analog-to-digital converter (ADC) performs the reverse operation.
