计算传输线路的串噪声值和分析通道一般传输特性对调频多路电话信号的影响找到了一条有效的途径。

Abstract

A theoretical formula to explain the intermodulation noise

which is produced by general transmission characteristics with higher terms in an analog microwave trunk

is obtained by use of the Bessel function expression. The usual equations for calculating the intermodulation noise in engineering practice are special cases of the presented formula. To analyze a general transmission characteristics with higher terms in microwave trunk

the least-squared principle is recommended and satisfactory results are obtained. Therefore

a good way to calculate the intermodulation noise in practical transmission systems and to analyze effects of the transmission characteristics in trunk on the FM multiplex telephony signal of radio relay systems are provided.
