How to convert brown waveform array into Orange Array

Hey, 

I'm trying to the the data from my array into a formla box so i want the indivdual values from this array but i've never come across the brown waveform wires 

I attached a paint file below i hope that helps explain what i mean

I want to go from finding the frequency & phase of my wave to being able to use thoes values in a calculation 

Thanks, i hope this makes sense.
