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.
The characteristic of color TV's picture spectrum ( of both joint and moving pictures ) is analysea on me 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.
