On a transmission line, the voltage wave is given by 8 8 V(L)=120exp(0.0025L)cos(10 t +2L)+60exp(-0.0025L)cos(10 t-2L), where L is the distance from the load. What is the reflection coefficient ? + - 對照 V(z)=V exp(-αz)cos(ωt-βz)+V exp(αz)cos(ωt+βz) + - 得V =60，V =120 - + Γ=V /V = 120/60 =2，這樣不就爆掉了問題在哪呢 ? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.249.157.51
