在信号传输时,功率是考虑的重要因素之一。在教材中最大功率传输定理的基础上,对正弦稳态下的最大传输功率做了更深入的讨论,得出了戴维南阻抗和负载在三种特殊限制条件下的最大传输功率。介绍了在负载不能任意改变的情况下,为实现最大功率传输而通常选用的三种 LC 匹配网络:“L”型匹配网络、“T”型匹配网络和“π”型匹配网络,并经讨论得出三种匹配网络本质上是一种网络,即“L”型匹配网络。
在信號傳輸時,功率是攷慮的重要因素之一。在教材中最大功率傳輸定理的基礎上,對正絃穩態下的最大傳輸功率做瞭更深入的討論,得齣瞭戴維南阻抗和負載在三種特殊限製條件下的最大傳輸功率。介紹瞭在負載不能任意改變的情況下,為實現最大功率傳輸而通常選用的三種 LC 匹配網絡:“L”型匹配網絡、“T”型匹配網絡和“π”型匹配網絡,併經討論得齣三種匹配網絡本質上是一種網絡,即“L”型匹配網絡。

In the signal transmission,power is one of the most important factors to be considered.The first part of the paper discusses on sinusoidal steady -state maximum power transmission on the basis of the maximum power transfer theorem,and works out the maxi-mum power transfer of Thevenin's equivalent resistance under three specific boundary conditions.The second part of the paper intro-duces three typical LC matching networks used to achieve maximum power transfer under the circumstances in which the load cannot be changed arbitrarily:the “L”matching network,the “T”matching network and “π”matching network,and discuss the three matching networks are essentially a network that is “L”matching network.
