Hi!!I want to scale an analogic signal, and I don´t understand very well how interpolated option works in "Scaling and Mapping".

[Bichillo]

Can anyone explain to me, the option Interpolated, in the function , "Scaling and Mapping?
Thank you!!!!!

When you select Interpolation you then define a table of value pairs; basically the raw data versus actual data.

For example
2 5
4 10
6 20
...

What the VI then does is if the input signal has a value of 3 the Express VI will linearly interpolate between 5 and 10 and will map your value of 3 to 7.5. Again a value of 5 would then be interpolated and mapped to 15.

Take a look at the attached VI.
