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.

  • 凯塞窗

    凯塞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.
