How can use JMP to decompose a curve into an original three-condition curve?

Hello, everyone!

The Y curve is the sum of the other three curves.
Specific formula is: Y = Max + mid + min + 10
If only know Y, I need to restore the three curves of "Max", "mid" and "min".
I've looked it up and it looks like I can do it with the Fourier transform.

I would like to ask if there is a corresponding module with JMP to achieve this restore.

The excel formula of the other three curves is:

min=ROUND(2*SIN(80*RADIANS(:x)+RADIANS(7)),10)+2
mid=ROUND(3*SIN(21*RADIANS(:x)+RADIANS(8)),10)+3
max=ROUND(4*SIN(5*RADIANS(:x)+RADIANS(64)),10)+4

Thanks!

Thank markbailey!

 

JMP is very powerful and I use very little of it.

I am just beginning to learn in this area.It's not so simple to switch to real data:

I tried FFT, FIT model, and time series.

I didn't turn on the right approach,

The trouble experts continued to guide me.

Thanks Experts!

According to Craige FFT analysis, the real curve should be divided into more curves.

 

I don't know how to adjust the parameters with the FIT model.

Thanks!
