摘要
本文提出并实验了一种用与彩色副载波锁相的4f_(sc)作为采样时钟,对电视测试信号进行实时采样和编码,由通用微机对电路进行控制和处理数据的计算机辅助测试系统方案。
This paper presents a computer aided test scheme of color TV receiver which samples the TV test signal in real-time method with 4f_(sc) whose phase is locked with color subcarrier and controls circuits and processes data by a micro-computer. Experiment based on the scheme is also done.
