In this article,it is described the calculation method of the signal to noise ratio for satellite broadcasting of an FM signal near or at threshold.It pointed out the mistake by Chun-loo in his caiculation about the optimum emphasis network in DBS system.The optimum pre-emphasis and de-emphasis networks are obtained with the method of optimization.It discussed the influences of the threshold charac- teristic by de-emphasis network and noise weighting,and the advantages of the new network given by this article,if the optimum filter proposed in this article is used in MAC system,the signal to noise ratio of luminance in MAC system is almost equal to that in PAL system,and the signal to noise ratio of chrominance in MAC system is increased by about 7 dB compared with that in PAL system.

本文给出调频传送的 MAC 制电视信号在门限或门限附近信噪比的计算方法。指出了 Chun-loo 关于 TV 卫星传输中最佳预加重网络的推导错误。应用优化技术得到最佳加重网络。讨论了主观加权和不同去加重网络对门限性能的影响,得出本文提出的新加重网络的优点。在 MAC 系统中使用本文提出的最佳滤波器,与 PAL 系统相比,亮度信噪比二者接近,而色度信噪比获7dB 左右的改善。

Introduces the feature,principle and transfer proceeding of MAC system of Satellite TV broadcasting.

介绍了卫星电视广播的MAC制的特点、原理及传送过程。
