// Given data
RmsVmax = 100; // max value of RMS vtg
RmsVmin = 25; // min value of RMS vtg
Zl = 300; // load impedance in ohm
// Calculations
VSWR = RmsVmax/RmsVmin;
// wkt VSWR = Zl/Zo; assuming Zl > Zo
Zo = Zl/VSWR; // charecteristic impedance in ohm
p = (Zl - Zo)/(Zl + Zo); // reflection co-efficient
// Output
mprintf('Reflection Co-efficient = %3.1f\n Charecteristic impedance = %d ohm',p,Zo);
