The examples provided in the documentation of following MATLAB Script function might use functions that are not available in MATLAB Script (e.g., plot, figure, subplot, wvtool, dfilt, fvtool, fdesign, RandStream). These examples are for illustration purposes and may not run successfully inside ...
Tab.3 Analysis results of harmonic measurement under the influence of white noise 由表3可见,在噪声影响下本文算法对谐波幅值、频率和相位的测量精度有所降低,但依然高于其余算法,并且满足相关标准的测量分析要求。 为进一步验证本文算法在白噪声影响下的测量准确度,对谐波信号在不同信噪比的白噪声下进行了仿真...

The two-sided amplitude spectrum P2, where the spectrum in the positive frequencies is the complex conjugate of the spectrum in the negative frequencies, has half the peak amplitudes of the time-domain signal. To convert to the single-sided spectrum, take the first half of the two-sided ...
The cubic spline function is used to approximate the amplitude ratio function, which can effectively suppress the fence effect and avoid solving high-order equations. The calculation accuracy is high. Through MATLAB simulation analysis, it is verified that the Rife-vincent self-convolution window ...
