摘　　要：本文的研究是基于文献［１］，但文献［１］中低通滤波器在视频通带内的群时延波动远远超过彩色电视系统的总体指标要求。本文提出了解决这一问题的一种均衡方法。The research of this paper is based on literature.In the Video pass band ,the group delay ripple of the low pass filter far exceeds the system designing limitation,which transmits colour television signals,This paper presents the equalizing method to solve the problem.The result of experiment proved this method to be correct.
