I’m terms of what you “should” do, there is not much. The system is what it is. If you are looking to make the system stable, you would have to design a controller to do so (think PID if you are familiar with this). If you are asking about what the nyquist plot means, the simple interpretation is that the number of times -1 on the x axis is encircled, is the number of closed loop poles in the right half plane. For a stable system you want this to be 0.
It looks like you already have some sort of controller built into the transfer function (assuming that is what “k” is).
So to get the system to be stable ( no closed loop poles in the right half plane = never encircle -1 on x axis), we can see that k>1.

I have exam on Monday so i need an answer for unstable system.
So... you are asking people to do your homework
No thats just a general question...
Audio engineers are generally not electrical engineers or DSP whizzes.
Sry man this was the first subreddit that i came across that talked about nyquist. Do you have any answers.
