The frequency-domain analysis is accomplished by fast-Fourier transformanalysis(FFTA)procedures and tested with a computergenerated mathematical model.
频域分析借助于快速富里叶变换分析（FFTA）过程，并用由计算机生成的数学模型进行测试。

As part of Alignment and Harmonization Analysis, you have to determine how to standardize and transform record structures to a given format, and how to match record instances.
作为校准和协调分析的一部分，必须确定如何将记录结构标准化和转换到给定的格式，以及如何匹配记录实例。

An example of a transform would be from an analysis model to a design model and then perhaps from the design model to code.
