主题
Get Started with Window Designer
- Use the Window Designer app to design and analyze spectral windows.
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.
