Differential Method and Differential Equation Method Applied to Spectral Analysis
Hong Chen · Journal of Electrical & Electronic Education · 2011
The implicit hypothesis of differential property applied to spectral analysis is discussed in this paper.The modification method is given,when this hypothesis is violated by the analyzed signal.Then,the differential equation description of generation system of the analyzed signal is derived.By means of it,signal spectrum is turned to the frequency transfer function of its generation system.The implicit hypothesis of the differential equation method is indicated.The modification method,when the hypothesis is violated by the analyzed signal,is also given.
