选定窗口的强度响应

比较窗口函数的傅里叶变换.

    
Wolfram Language code: windows = {DirichletWindow, BartlettWindow, KaiserWindow, HannWindow, HammingWindow, BlackmanWindow}; f = Table[FourierTransform[win[x], x, w], {win, windows}];
Wolfram Language code: Partition[MapThread[LogLinearPlot[Evaluate[20 Log[10, # / Limit[#, w -> 0]]], {w, .1, 100}, GridLines -> Automatic, PlotRange -> {Automatic, {0, -80}}, PlotLabel -> #2]&, {f, windows}], 3]//Grid
