【 摘 要 】

S-parameter measurements of microstrips and striplines were done. The physical properties of the devices under test, consisting of nine single coplanar traces and nine pairs of coupled coplanar traces, are provided. The lab setup and equipment used to make such measurements are explained along with labeled pictures for visualization. Next, with the measured data, the limitations of the discrete Hilbert transform were tested. The results show the kind of properties frequency response data should have in order for the discrete Hilbert transform to correctly determine whether the data is causalor not.
