摘要
在ＭＰＥＧ－２中已制定了有关ＨＤＴＶ的国际标准，世界上已经研制出不少ＨＤＴＶ产品，但对于ＨＤＴＶ亮度信号的二维频谱分析的研究不多，因此推导出ＨＤＴＶ亮度信号二维频谱及二维幅频特性的数学模型及二维谱图形。
In MPEG-2, related international standard on HDTV has been prepared, a lot of HDTV products have been developed in the world, but very little research has been done on two dimensional spectrum analysis of HDTV luminance signals. Therefore, the mathematical model and the figure of two dimensional spectrum are derived in this paper.
