Hi,
not sure if this is correct place to put this but here goes.
I was having a discussion about bode plots and it was stated that you cannot estimate the phase plot using the magnitude plot. For example, say you only have information about the magnitude, you can't tell what the phase is.
IMO, this should not be true, as I would suspect that the phase should follow the magnitude plot. For example, if you had a pole on your magnitude plot, I don't think there would be a case where the phase increases 90 degrees (as opposed to decreasing 90 degrees).
Who is correct? I'm fairly certain that with just magnitude information, you can at least get a good estimation of the phase plot. Am I missing something here?
