Filename: samplerateconversion.vi
This VI accepts a waveform acquired at a given sampling rate and produces the same waveform whose samples appear to have been acquired at a different rate.
The VI accepts the following inputs:
1) the input array for the original waveform
2) the sampling rate at which you acquired the original data
3) the desired sampling rate for the waveform.
The VI returns an output array with the newly sampled waveform.
