本文介绍了用于通信应用等ADC多音测试中准确确定互调失真产物的多音曲线拟合算法。我们的曲线拟合算法的准确性相干采样（输入频率已知）和非相干采样（输入频率未知）的数值模拟进行了验证。我们发现，特别是不相干的采样，这些算法提供了更好的精度比传统的（单音）曲线拟合算法。© 2003 Wiley Periodicals，Inc. Electron Comm Jpn Pt 2，86（8）：1-11，2003;在线发表于Wiley InterScience（www.interscience.wiley.com）。DOI 10.1002/ecjb.10148
This paper describes multitone curve-fitting algorithms for accurate determination of intermodulation distortion products in the multitone testing of ADCs used in communication applications and the like. Accuracy of our curve-fitting algorithms for coherent sampling (input frequencies known) and incoherent sampling (input frequencies unknown) was validated by numerical simulations. We found that—especially for incoherent sampling—these algorithms provide better accuracy than conventional (single-tone) curve-fitting algorithms. © 2003 Wiley Periodicals, Inc.
