Random Response Analysis (dB/octave to ((m/s^2)^2)/Hz)

Hi there,

 

As of my knowledge for doing a random response analysis we require a ASD Vs frequency curve.

 

But here I have the 'ASD slope' values (units= dB/Octave) and frequency range.

 

Can any one please tell me how to get 'ASD' values from 'ASD slope' values.

 

Is there any direct formula to convert them.?

 

I have referred the following site for that but I didn't understand.

And also Can any one tell me what is the Verification process for random vibration analysis theoretically. If not with a sample problem,,..

 

Thanks in advance
