The condition for a quarter wave transformer is(a) Zo^2 = Zin ZL(b) Zo

1.	The condition for a quarter wave transformer is(a) Zo^2 = Zin ZL(b) Zo = Zin ZL(c) ZL^2 = Zin Zo(d) Zo = ZinThe question was asked by my college professor while I was bunking the class.I want to ask this question from Transmission Line Equations in chapter Transmission Lines of Electromagnetic Theory
Answer» Right ANSWER is (a) Zo^2 = Zin ZL The best I can EXPLAIN: The QUARTER wave transformer represents L = λ/4. In this case, the characteristic impedance is the geometric mean of the input and load impedances. THUS Zo^2 = Zin ZL is the required condition.
