Periodic PCR profile in Formula Node

[Wingston]

I use Formula Node to build a three-stage temperature profile in LabVIEW v7.


if (x>=0&&x<5)
y=94;
if (x>=5&&x<10)
y=56;
if (x>=10&&x<15)
y=72;

How to make this signal become periodic?
You can find my VI in the attachment.

If you mean periodic on x, then adding before your calculations expression
x=mod(x,15);
can work (as this will make argument always wrap in [0,15) ).
