[edit] Nichols != Nyquist

Ahem! the Nichols plot and the Nyquist plot are not the same AFAIK, contrary to what is stated here. Maybe examples of these plots would make that clear. A different engineer indeed. Encyclops 16:08, 20 August 2006 (UTC)

I'm with you on that one. They are similar in that they both plot the magnitude and phase of the response with frequency as a parameter. However the Nyquist plot is done on a polar plot whereas a Nichols plot is the log of the magnitude versus phase.
I'm currently studying for my end-of-year exams... one of my exams is half control theory and so I have these plots coming out my ears. Give me a couple of weeks till the exam period is over and I'll rewrite this including examples.
