摘要
微分相位失真是由传输系统的非线性引起的,它会造成彩色图像信号随亮度信号变化而引起色调失真,电视信号在传输的过程中总存在着非线性,它不仅会产生微分增益失真,同时还会产生微分相位失真、互调失真等,着重介绍的是微分相位失真。
Differential phase distortion is composed of a transmission system caused by nonlinear, it will cause the color image signal with the luminance signal caused by the changes of tonal distortion. A television signal in the transmission process, there are always nonlinear, it can not only generate differential gain distortion, but also produce differential phase distortion, intermediation distortion. This paper introduces the differential phase distortion.
