This paper presents a "waveform display method" for checking the colour TV Chrominance Delay Line in the factory, and introduces a simple, practical and self-made test-signal generator.
Applying the theory of multi dimensional digital signal processing, this paper analyses the 2-dimensional interleaving structure of luminance and chrominance spectrum for the PAL signal.
运用多维数字信号处理理论，分析了PAL信号亮度和色度频谱的二维交错结构。

In detail, there is reported on the achievable improvement of picture sharpness and signal-to-noise ratio as well as on the reduction of flicker effects and luminance-chrominance-interference.
