本文提供了一个简明的审查数据窗口和它们的影响检测谐波信号的宽带噪声的存在下，并在附近的强谐波干扰的存在下。我们还提请注意一些常见的错误，在应用程序的窗口时，使用快速傅立叶变换。本文包括一个全面的目录数据窗口沿着其显着的性能参数，从不同的窗口可以进行比较。最后，一个例子演示了窗口的使用和价值，以解决密集的谐波信号，其特点是幅度差异大。
This paper makes available a concise review of data windows and their affect on the detection of harmonic signals in the presence of broad-band noise, and in the presence of nearby strong harmonic interference. We also call attention to a number of common errors in the application of windows when used with the fast Fourier transform. This paper includes a comprehensive catalog of data windows along with their significant performance parameters from which the different windows can be compared. Finally, an example demonstrates the use and value of windows to resolve closely spaced harmonic signals characterized by large differences in amplitude.
