斜坡类信号频谱分析时应注意的一个问题
A problem about the spectrum analysis of ramp signal
摘要
Abstract
Fourier transform of ramp signal, a kind of power-infinite signal, commonly appears in many complex function and integral transformation related textbooks. However, some have questioned the existence of Fourier transforms for power-infinite signals, contending that the spectral characteristics of their transformations lack theoretical significance and practical application. By analyzing the basic definition, computational characteristics, and physical significance of the Fourier transform, along with the frequency characteristics of ramp signals, it is proposed that, in the process of signal spectrum analysis, Fourier transform may not be applicable to power-infinite signals.关键词
