From theoretical analysis , we know the existing demodulation methods have limitations as following : one is that the subtraction of the two signals frequencies will display as the result of demodulation when we demodulate two time - domain adding signals without modulating information ( fault information ) ; the other one is that aliasing phenomenon will occur as a result of getting absolute value , detection or square in the process of generalized demodulation analysis , such phenomenon will result in some superfluous frequency composition on the frequency spectrum , which will puzzle the detec tion of mechanical vibration . if the sampling frequency is selected from a suitable range , the aliasing phenomenon will be avoided ; the last one is that aliasing frequencies will be produced in zoom demodulation analysis because this algorithm cannot employ digital low - pass filtering to avert the folding frequencies of higher harmonics in the process of zoom sub - sampling
现有的解调分析方法存在以下三种局限性：将不包括调制信息(故障信息)的两时域相加信号，也以其频率之差作为解调信号而解出；广义检波滤波解调分析中，由于取绝对值、检波或平方过程可能产生混频效应，在解调谱中表现为无法分析的频率成分，并由此推导出避免这种混频现象的采样频率的选取范围，从根本上避免此类误诊断的产生；几种细化解调分析新算法中，因为无法在细化分析的选抽时进行数字低通滤波，有可能会出现调制频率的高次谐波成分发生频率混叠而反折到低频部分的现象。
