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象频谱的性质 ,得出电视图象 (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 mf H 附近的狭窄频带内的结论 。
This paper analyzes the nature of TV picture spectrum(of both static and dynamic pictures) on the basis of Fourie Expression,concludes that most spectrum energy of TV pictures (both static and dynamic) lies within the narrow frequency band near line and multiple frequencies mf H,thus suggests increased use of high spectrum.
