本文探讨用导频快慢调兼用的方法,减少载波机多个自动电平调整系统过调的理论。以差分方程及留数定理等求出自速相同、自速不同、两种自速及最佳系统(末快调)电平变化过程,并对最佳系统进行特性分析及计算。最近进行了实际测试,证明本文的理论是正确的。小同轴300路等载波系统也采用末快调最佳系统以减少过调。
This article discusses the use of pilot fast and slow adjustment method used to reduce the number of Carrier Automatic Level Adjustment System over-tuned theory. Based on the difference equation and the residue theorem, the process of changing the self-speed and the optimum system (final speed) with the same speed and different self-speed is obtained. The optimal system is analyzed and calculated. Recently conducted a practical test to prove the theory of this article is correct. Small coaxial 300-channel carrier systems such as the other also use the end of the best system to reduce overshoot.
