| 摘 要： | 本文介绍了一个色度信号不均匀压缩的时分制模拟彩色电视信号编码和解码系统的实例。给出了用这个系统对彩条信号进行编码和解码的实验结果。并在广播电视制式标准条件下,将这一结果与色度信号均匀压缩的时分制系统的结果进行了比较。实验表明:前者起到了频率匀化的作用,可以把时间压缩后的色信号的带宽限制在所要求的通常范围之内。文末讨论了噪声对信号传输的影响。

| Abstract: | Based on the idea introduced in a companion paper, weh ave developedaTDM analog video signal system, in which the chrominance signalis compre-ssed along the time axis with the modulated clock pulse by the luminancesignal. The experimental results using this system as well as the block-diagrame of this system are presented in this paper. These results haveproved that the frequencies of the compressed chrominance singal becomehomogeneous and can be limited to the bandwidth required by the Tele-vision System Standard. |
