摘要
从数学角度论证了数字化梳状滤波器Y/C分离的可行性,推导出其基本的电路模型及幅频特性,并列举了当前数字化彩电中具有代表性的自适应多制式单片动态数字化梳状滤波器芯片实例.
It is demonstrated in detail that feasibility of the digital comb filter of the separation of luminance signal and color signal from the view of mathematics,and its basic model of circuit and the characteristic of range of frequency is drived out,and muti-system one chip self-adaptation dynamic digital comb filter which is the representative of present digital color TV is enumerated.
