A 50歐姆 lossless transmission line is transmitting a signal from a voltage supply (which has a resistance of Rg=25歐姆) to a load with an impedance of ZL=35-j20歐姆. Please determine the shortest possible length of the line in terms of λ so that it can transfer the maximum average power from the supply to the load. 有大大能幫解一下這題嗎 感謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.113.193.6

要得到最大功率 就是你看進去的阻抗要和電源阻抗匹配

可是題目是要用單支幹 還是要用阻抗匹配呢...?
