WebNote 2: Infinite gain or phase margin is good. Note 3: If the gain crossover frequency is after the phase crossover frequency (I.e. negative GM and PM), the system is unstable Note 3: Often better to measure PM and GM from Nyquist as if the phase crosses the -180 degree line multiple times, don’t know where to measure frkm
