| 摘 要： | 本文首先推导出载波增音机环路衰耗的普遍公式,然后讨论四线制增音机的环路衰耗由什么组成,环路衰耗与增益波动的关系,四线制增音机为什么可以不考虑环路衰耗。二线制增音机的环路衰耗主要由方向滤波器的阻带衰耗组成。为了保证增益波动较小,本文讨论方向滤波器阻带的衰耗应如何决定。

| Abstract: | First, this paper derives the formula of circle's attenuation of carrier repeater; then, it is to discuss the constitution of circle's attenuation of four- wire repeater, the relation bet- ween circle's attenuation of repeater and amplification, and why the four- wire repeater neglects the circle's attenuation. The cricle's attenuation of two-wire repeater is principaly of the attenuation of directional filters composed. To gua- rantee small amplificational ripple, this paper is to discuss how to determine the attenuation of directional filters. |
