impedance matching problems
He is very ambiguous in what he is asking about in 2nd ed problem 3.1.
Any directions will be appreciated. I have read the chapter very properly and understand the L-match etc but cannot figure out what is he talking about.
It seems like some important point the seniors must know.
Consider two approaches to matching a purely resistive 75 Ohm load to a source whose impedance at some frequency happens to be 50 + j 10.
A) Downwardly mobile engineer A, after reading about the maximum power transfer theorem, dutifully adds a 25 Ohm resistor and a capacitor of - j I0 in series with the source,
B) engineer B offers a similar solution but replaces the 25 Ohm resistor with an appropriateIy designed L-match.
Quantitatively compare the two approaches by computing expIicitly the ratio of
powers delivered to the 75 Ohm load by these two solutions, assuming equal Thevenin source voltages. Qualitatively explain the reason for the difference, and why engineer A can look forward to a long career at SubOptimal Products, Tnc.
