前級後級阻抗匹配

看了很多關於前後級匹配的文章，這個很淺白易懂易明

其實應該先學下乜野係Max. power transfer
https://circuitglobe.com/what-is ... ansfer-theorem.html
其中一段講：
The concept of Maximum Power Transfer theorem is that by making the source resistance equal to the load resistance, which has wide application in communication circuits where the magnitude of power transfer is sufficiently small. To achieve maximum power transfer, the source and the load resistance are matched and with this, efficiency becomes 50% with the flow of maximum power from the source to the load.

但在音響世界要好聲或適合用家聽的聲時就會不理甚麼叫maximum power transfer，好聽就是王道！

我都係讀孖E識小小原理，太理論又d又t比較難明，通俗冇咁理論易明好多.
