一、概述为了在电视接收机屏幕上得到高质量的重现图像,在调试接收机时,常常采用各种图像信号发生器。例如多波群信号,灰度阶梯信号,方格,棋盘,园等信号,彩色电视所用的彩带信号等。用这些信号调试电视接收机既直观又准确,而且能迅速发现接收机的毛病所在。 I. Overview In order to get high-quality reproduced images on the television receiver’s screen, a variety of image signal generators are often used when debugging the receiver. For example, multi-wave group signals, grayscale signals, squares, checkerboards, parks and other signals, color television signals used in ribbons. Debugging TV receivers with these signals is both intuitive and accurate, and quickly reveals the problems with the receiver.
