Hi;
There is a VI specifically for thermocouples. Look for it in the function palette under:
Data Acquisition -> Signal ConditioningThere are windows and filters under:
Analyze -> Signal ProcessingOf course, you can also use the tools under Mathematics, (for example, look under Probability and Statistics) to create your own signal conditioning code.
If for some reason can't find this, probably you have a limited version of LabVIEW.
