一、引言付氏分析和谱估计的一个中心问题是根据信号 f(t)的有限段来确定其变换:F(ω)∫_(-∞)~∞=f(t)e~(-jωt)dt (1)其中 f(t)的有限段为g(t)=
I. INTRODUCTION One of the central problems in the Fourier analysis and spectral estimation is to determine its transformation according to the finite segment of the signal f (t): F (ω) ∫ _ (- ∞) ~ ∞ = f (t) e ~ (-jωt ) dt (1) where the finite segment of f (t) is g (t) =
