摘要
讨论了量化误差对周期信号失真度测量评价结果的影响 ,详细阐述了两者之间的关系 ,并给出了量化误差对周期信号失真度测量造成的影响及其修正关系的数学公式。在正弦波失真度评价中进行的仿真实验结果 。
In this paper, the influences of the quantization error to the evaluation of the distortion of periodic signal are described, the relationship between the quantization error and the distortion evaluation results are discussed in detail. And then, a correction method and formula of the influences of quantization error in distortion evaluation of periodic signal are given. Some imitation results on sine wave and its distortion evaluation show the effectiveness of this approach.
