3. Consider a lossless transmission line of a characteristic impedence Ro.
A time-harmonic voltage source of an amplitude Vg and an internal
impedence Rg=Ro is connected to the input terminals of the line , which
si terminated with a lord impedence Zl=Rl+jXl.
第一小題問的是 write the line voltage and current phasor expressions V(z)
and I(z)
答案為什麼是 V(z)= Vg/2 * exp^-jβz + Vg/2 * Γ * exp^-2jβL*exp^jβz
而不是 V(z)=Vg/2* ( exp^-jβz + Γ exp^jβz ) 呢?
請高手解答~謝謝!
