Hello,
I am facing an unusual issue with bode plot. I am finding Bode of a transfer function.
From the plot it seems that a system is stable but the marker on the plot claims it unstable. Could anyone suggest/comment why is it so? Should i consider it stable or unstable? I am attaching the plot below.
Thank you.
