Expression for input impedance of a transmission line in terms of load impedance and characteristic impedance is: Correct Answer Z0 (ZL+j Z0tan βl)/ (Z0+j ZLtan βl)

Representing the input voltage as the ratio of voltage at current, representing voltage and currents in hyperbolic function form and simplifying, we get Z0 (ZL+j Z0tan βl)/ (Z0+j ZLtan βl).
