Pyplot是Matplotlib模块的基于状态的接口,该模块提供了MATLAB-like接口。在Pyplot中可以使用各种图,例如线图,轮廓图,直方图,散点图,3D图等。 matplotlib.pyplot.phase_spectrum()函数: matplotlib库的pyplot模块中的phase_spectrum()函数用于绘制phase_spectrum。通常,它计算序列的phase_spectrum并完成绘制。 用法:phase_sp...
title('Phase Spectrum'); ``` 在示例中,我们首先生成了一个包含两个频率成分的信号x。然后使用phase函数计算x的相位谱y。最后,使用plot函数绘制了y的相位谱图。 通过理解和分析信号的相位谱,我们可以更好地理解信号的频率成分和相位特性,进而实现更多高级的信号处理和分析任务。使用phase函数可以方便地计算信号的相...

i.e., the magnitude spectrum decays as Ω increases. The following script gives the necessary instructions to compute and plot the signal x1(t) and the magnitude and phase of its Fourier transform using symbolic MATLAB. Similar calculations are done for x2(t). Sign in to download full-size...

Apply a frequency offset to a phase-coded waveform that uses the Zadoff-Chu code. Plot the frequency spectrum of the waveform with and without a frequency offset applied. Create a phase-coded waveform object which is configured to set the frequency offset from an input when the object is exec...
(figure on the right). Each colour represents a different channel because the signal exists of 3 components(x,y and z) but it is ok to just look at the blue spectrum(component x). As you can see the pspectrum supresses the noise much better than that of a normal fft or am i ...
Fault phase selection is studied in this paper based on the wavelet power spectrum entropy and LIBSVM for transmission line. First, MATLAB is used to simulate five fault types and obtain a variety of fault voltage waveforms. Second, the simulation waveform is transformed to extract the energy sp...
View Phase Noise Effects on Signal Spectrum View the effects of phase noise on a 10 MHz sine wave by using a spectrum analyzer. Adjust the resolution bandwidth of the spectrum analyzer to see its impact on the visualized spectral noise. ...
However, any amount of added noise (even in noiseless cases, given the computational precision of MATLAB) would give nonzero phases in places where it should be zero. In this case, since we know that the magnitude spectrum is significant at the negative and the positive values of the ...
