彩色电视图像信号的频谱分析

Spectroanalysis of Picture Signal for Color TV

摘要: 在导出电视信号频谱的傅立叶表达式的基础上,分析了静止和活动电视图像频谱的性质,得出电视图像(包括静止的和活动的)的频谱能量大部分集中在行频及其倍频mfH附近的狭窄频带内的结论.

Abstract: The characteristic of color TV's picture spectrum(of both joint and moving pictures) is analysed on the basis of Fourie Expression,it is concluded that most spectrum energy of color TV's pictures(both joint and moving) lies within the narrow frequency band near line and multiple frequencies mfH.
