论文摘要
这项工作旨在将直接数字合成器（DDS）及其模拟对应物的比较指标联系起来。提出的指标是总谐波失真（THD）和最大绝对误差。理论上将误差用于封闭形式，以用于DDS的已知系统参数，采样率和位计数。通过使用MATLAB脚本，为广泛的参数扫描模拟了系统模型。
This work aims to relate comparison metrics for both Direct Digital Synthesizers (DDS) and their analog counterparts. The proposed metrics are Total Harmonic Distortion (THD) and maximum absolute error. Error is theoretically formulated into closed forms for known systematic parameters of DDS, sample rate, and bit counts. By the use of Matlab scripting, the system model is simulated for a wide range of parameters sweep.
