I have frequency spectrum which looks as such:



Below -40dB (as shown in red box), the data can be seen to have noise components.

How do we locate this (-40dB) without plotting the graph in Python?

If somebody could please let me know how do we go about this, I would be very much thankful.

Hi Ranjan ...

Ehm that quite the questions ... 😜 
I guess it depends on how you get the data (in what format) ?
