in time? draw the phase of S11, it shows the relative phase delay in frequency domain.calculate the phase delay in time domain with it. (remind: 360degrees=1cycle=1/f in second)) take care of phase transmission between -180deg. and 180deg. you should count it as a whole cycle.nckwang said:i want to know group delay of S11, but i dont know how go get it, can anyone help me?
GD = -(1/360) * (dphi/df),
phi [deg], f [Hz]
df - aperture is frequency-delta used to calculate GD
wider aperture: lower noise / less resolution
narrower aperture: more resolution / higher noise
