Maximze power delivered to load (lossless tranmsion line)
ok, my professor explained this to me so obviously i was doing this wrong. If I use the equation he gave me, Pavg=\frac{1}{2}Re(V x I*)=\frac{1}{2} Re[\frac{Vg}{Zg+(Rin+Xin)}((Rin+Xin)(\frac{Vg}{Zg+(Rin-Xin}))] where i substituted Zin=Rin+Xin and use Vg=Vo and I ended up with 1/2...- nagr

Maximze power delivered to load (lossless tranmsion line)
the general equation for Zin in my book is Zin=Z0(\frac{zL+j(tan(βl)))}{1+j(zL*tan(βl))}) where zL=\frac{ZL}{Z0} but i don't think this helps me much. for problem (b), this is what I did so far: since length of line is a special case l=\frac{λ}{4}, i used the equation for Zin I listed and got...- nagr

Maximze power delivered to load (lossless tranmsion line)
Homework Statement Homework Equations Time Avg. Power = \frac{|V0+|^2}{2*Z0} [1-|\Gamma|^2] for line of l=\frac{λ}{4}+n\frac{λ}{2} (where n=0 here), Zin=\frac{Z0^2}{ZL} The Attempt at a Solution Bit confused what to do in the 1st part? I know that max. power is delivered to load when...- nagr

Engineering Find V(L) for Lumped vs distributive circuits
the only equation i see in my book is V(z)=V0+(e-jβz)+V0-(ejβz) at the load voltage VL is at z=0 and given by V0+ + V0- V0+/V0- are related to reflection coefficient by: V0- = \GammaV0+ to find V0+ i would have to find Zin. where Zin=Z0[(zL+jtanβl)/(1+j(zLtanβl)] where zL=ZL/Z0=4 and...- nagr
