Question:

A 50-Ω air slotted line is applied in measuring a load impedance. Adjacent minima are found at 14 cm and 22.5 cm from the load when the unknown load is connected and Vmax = 0.95 V and Vmin = 0.45 V. When the load is replaced by a short circuit, the minima are 3.2 cm to the load. Determine s, f, T, and ZL.
