使用plot函数绘制频率响应的幅度曲线。根据需要,可以添加图例、标题和坐标轴标签。 matlab figure; plot(w/pi, abs(h)); % 绘制归一化频率下的幅度响应 xlabel('Normalized Frequency (\times \pi rad/sample)'); ylabel('Magnitude'); title('Frequency Response
For discrete-time systems, thebodeplotfunction evaluates the frequency response on the unit circle. To facilitate interpretation, the command parameterizes the upper half of the unit circle as: z=ejωTs, 0≤ω≤ωN=πTs, whereTsis the sample time andωNis the Nyquist frequency. The softwa...

(nonparametric model) and then plot the spectral analysis result on top of the frequency response of the parametric models. Because nonparametric and parametric models are derived using different algorithms, agreement between these models increases confidence in the parametric model results. For an ...
