WebOct 2, 2014 · 1. A sinewave shifted by 360° is indistinguishable from the original sineweave. Therefore, any phase measurement is going to be limited to a total range of 360°. Some methods will give you an answer between -180° and +180°, while other methods will give you an answer between 0° and +360°. WebNegative phase margin does not imply anything about stability by itself. You have to be around the -1 point too to go unstable. Similarly with gain margin. Note that, these are rough indicators of stability. A complex number can push the locus such that it crosses -1 point (compared to a pure phase shift or gain change).
