摘要
本文从Fourier级数的展开式及Fourier变换两个角度出发,利用Parseval定理分别求解了在工程物理学及信号分析学中常用到的两类积分。这两类积分的求解,不仅给广义积分的求解提供了新的思路,而且丰富了Parseval定理的应用。
From the two angles of Fourier series expansions and Fourier transform, this paper solves two kinds of integrals which are often used in the engineering physics and the signal analysis by Parseval theorem. Not only a new method about the generalized integrals is obtained, but also the application of Parseval theorem bas been enriched.
