if statement

[Bob94]

I want to condition my data using signal express.  if x<0 then x=0.  I would like to make the limit (0) a user specified value.  Can I do the in SE, or is there a labview VI that I can use?

I do not know anything about SE but in LabVIEW that can be done with the In Range and Coerce function. Set the lower limit to zero and the upper limit to +inf.

or create a boolean array b=x>0,  convert to 0,1 and multiply your data  x*b ...

Thanks for the input.  As far as I know I can't do any sogical functions such as (>,<, etc) in signal express.  Your comments did however give me an idea that worked.  I used the analog-to-digital function, then the digital-to-analog function and arithmatic to accomplish the same thing.  It is a pretty convoluted method, but is equivalent to what you suggested.  It is awkward.

Thanks for your help.     Bob

You really should have posted your question to the se board. It has nothing to do with the NI signal conditioning hardware. There might not be a way to do what you want but at least it will be read by the right people.
