主题

加窗法

了解频谱窗以及如何使用工具箱函数分析它们。

Generalized Cosine Windows

Blackman, flat top, Hamming, Hann, and rectangular windows are all special cases of the generalized cosine window.

Kaiser 窗

Kaiser 窗旨在最大化主瓣能量与旁瓣能量之比。

Chebyshev Window

The Chebyshev window minimizes the mainlobe width for a particular sidelobe level and exhibits equiripple sidelobe behavior.
