Convert Sparameters to RLGC transmission line parameters
rlgc_params = s2rlgc(s_params,length,freq,z0)
rlgc_params = s2rlgc(s_params,length,freq)
rlgc_params = s2rlgc(s_params,length,freq,z0)
transforms
multiport Sparameter data into a frequencydomain representation of an RLGC transmission
line.
rlgc_params = s2rlgc(s_params,length,freq)
transforms multiport
Sparameter data into RLGC transmission line parameters using a reference impedance of
50 Ω.
