Hey all,
I was wondering if anyone can think of a way to generate vibration profile curves using matlab similar to this example:

This is written really well but it offers no actual explanation of how these curves would be created, I'm assuming you couldn't do this with a particular function and probably have to hand pick 'breakpoints' and then just plot them?
Thanks! JT

Is PSD just determined experimentally for certain frequencies? That's what the graph look like at least.
