摘要
本文基于PAL信号的频谱特点,分析了由2H延迟线组成的梳状滤波器分离亮度信号的原理,给出了实验电路框图,并简要叙述了误差带来的影响。
On the basis of Spectral performance of PAL signal, the separation of luminance signal using the comb filter composed of 2H delay line is discussed. The block-diagram of experimental circuit is given. The effects of error is analysed.
