| Abstract: | Based on the spectral distribution characteristic of the PAL television signal, the paper describes several digital filter methods. The adaptive 3-lines comb filter is applied in the experiment. The vides luminance and chrominance signals have clear staircases and steep edge after applied with digital YC separation and UV demodulation, which indicate that the YC separation is more throughful. |
