本文用二维Walsh变换处理了NTSC和PAL彩色全电视信号。用解析式和矩阵形式给出其二维序谱分布。指出用二维Walsh变换可将NTSC或PAL中亮度信号和色度信号分离开。提出了二维Walsh函数正交平衡调幅制。所得结果可用于彩色全电视信号的数字分离、解调和数字传送。
In this paper, two-dimensional Walsh transform has been used to process NTSC and PAL full color television signals. The two-dimensional spectral distributions are given in analytical and matrix form. The two-dimensional Walsh transform is used to separate the luminance and chrominance signals in NTSC or PAL. Proposed two-dimensional Walsh function orthogonal balance amplitude modulation. The results can be used for digital full color TV signal separation, demodulation and digital transmission.
