Webbwhich has very wide capability. Basically, it writtenis as plot(x, y), where is ytaken to be a function of x. Figure 1 shows a simple example given by: >> x = 0:0.1:8; >> y = 8*exp(-1.1*x); >> figure >> plot(x, y) Figure 1 . Alternatively, if and x y are defined as independent vectors, they must have the same length: >> x = 0:1:8; Webb7 aug. 2024 · 总结一下:. 频谱泄露由截断加窗导致,可以考虑一个单频信号,频谱为一条谱线,加窗后,频谱为窗函数频谱(比如Sa函数)的移位(中心频率移到原单频信号的频率处),原来的谱线能量发散了,这个就就叫频谱泄露;由于DFT默认会对信号周期延拓,对 …
