Return true if rationalfit output is passive at all frequencies
Read the file,
passive.s2p and fit the 2-by-2 S-parameters.
S = sparameters('passive.s2p'); fit = rationalfit(S);
Test the passivity of the 2-by-2 fit.
ans = logical 0
Plot the passivity of the 2-by-2 fit.
figure passivity(fit,[1e9 40e9])
result— Result of passivity test
Result of passivity test of the
object, returned as
result tells you if the
fit can result in unstable
maxfreq— Frequency at which norm(H) is equal to maximum value
Frequency at which norm(H) is equal to maximum value, returned as a scalar in hertz.
maxvalue— Maximum norm(H) over frequencies (0,Inf)
Maximum norm(H) over frequencies (0,Inf), returned as a scalar.
