摘要
用二维离散傅里叶交换研究了特殊取样ＮＴＳＣ彩色信号的三维谱。分析了２ｆｓｃ取样下的两种取样结构，并且讨论了重建问题。
The three-dimensional spectrum of special sampled NTSC color signals is studied with the aid of two-dimentsional discrete Fourier transfler.Two sampling structures which allow afsc horizontal sampling rate are analyzed,and their reconstructions are discussed.
