视频信号处理放大器是广播电视中心的主要设备之一,一般安装在中心控制室的视频信号输入输出端口、发射台视频信号输入端口以及较长距离传输的中间环节,用以补偿传输过程中产生的损耗和校正畸变,改善视频信号的质量.本文将对视频信号处理放大器的墓本组成和工作原理作一些介绍.视频信号处理放大器一般包括:输入均衡放大级、视频信号处理单元和同步信号处理单元等部分,如图1所示.
Video signal processing amplifier is one of the main equipment of the radio and television center, usually installed in the central control room of the video signal input and output ports, transmitter video signal input port and the middle of a longer distance transmission to compensate for the transmission process generated Loss and distortion correction to improve the quality of the video signal.This article will introduce the composition and working principle of the video signal processing amplifier.This video signal processing amplifier generally includes: input equalization amplifier stage, video signal processing unit and synchronous signal processing unit And other parts, shown in Figure 1.
