continuous to discrete

[atoz]

Hi,

I am kind of new to labview and need some help. I obtained a set of data(x,y) of a graph and save in lvm file. Then I use the read from measurement file vi and obtained the signal. what I am trying to do is to discretize this signal to a certain time step (i.e. x start from 0 with interval 10). Is there anyway I can do this?

Discretization in time axis is nothing but sampling, if you've a set of data (an array), and want to perform discretization (in time), you can use decimation tool.

Thanks for replying. but what I want is something like this. for example i have a set of data (both in x and y). example:

x              y

10.123     2345

18.34      3456

29.89      4678

.

.

.

with these data, i use the curve fitting vi to get the fitted curve with new set of data (both x and y). however, i would like to get the value of y for a fix interval value of x based on the fitted curve data. example for time step x = 10, is there a way of doing that?

There is a direct tool available, check the attached code.

It seems that I am not able to open the file. I am using 8.6 version. Do you have that vi in 8.6 version?
