Question A-007-002-002

What kind of impedance does a quarter wavelength transmission line present to the source if the line is open at the far end?

Correct Answer

A very low impedance

Explanation

An open-circuited quarter-wavelength (λ/4) transmission line acts as an impedance inverter; it transforms an open circuit (very high impedance) at the far end into a short circuit (very low impedance) at the input.
