plot(f, y); xlabel('Frequency (Hz)'); ylabel('Phase (rad)'); 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...
matlab code(frequency response)如下: omega = -2*pi:pi/400:2*pi; H5 = ((1/5)*(1-exp(-1i*omega*5))./(1-exp(-1i*omega))); plot(omega,abs(H5)), title('frequency response'); 結果的圖如下 matlab code(phase response)如下: omega = -2*pi:pi/400:2*pi; H5 = ((1/5)*(1...
