SAA4961在色亮分离电路中的应用

Application of SAA4961 in the Circuit in which Color Separating from Lum

SAA4961是飞利浦公司推出的一种NTSC/PAL制兼容的三行自适应梳状滤波器.其输出亮度信号不需要通常的色度陷波器,增加亮度信号的带宽,可以有效消除“色串亮”和“亮串色”等现象,大幅度提高彩电的清晰度.

SAA4961 is a NTSC/PAL compatible three-capable self-adapt pectinate fliter produced by Philips, in which the luminosity signals can be output without using chroma filter, and the bandwidth of luminosity signals is increased, and the phenomena of ＂color enter luminosity＂ and ＂luminosity enter color＂ and so on are effectively eliminated, and the clarity of the color TV is greatly improved. This article introduces the application of SAA4961 pectinate filter circuit.
