摘要:
非线性调制函数的频谱特征分析在工程中具有广泛的实用价值。本文借助 Bessel 函数详细分析了非线性调制(调幅、调频)信号的频谱特性及相位相关特性;概括了用双谱分析非线性调制信号时频谱规律,进而求出应用双谱进行信号主频及调制频率的谱识别方法。通过对步进电机转速误差的双谱分析,验证了该方法的可靠性。
Abstract:
The spectral analysis of nonlinear modulation function is more practical and available.In this paper,the spectrum and phase relations of nonlinear modulation (frequency modulation and amplitude modulation) functions are presented in detail by using Bessel functions.The bispectrum of these said functions are also developed in this paper.By this,a new method to identify the modulated frequency and modulating frequency is presented.Furthermore, this method is applied to analyze the error of the rate of a step-motor and the results convince it available.
