[Patrick D. <pat...@la...>]

Hello,

I would like to know if you have foreseen to better identify the forbidden
area into the black-Nichols chart as show into the attached file (bold line
with closed loop gain at +2.3dB).
ALternatively, do you know how to proceed ?

Thanks for your help and for this very interesting module.

Patrick.
