Cross Correlation

[gplevnik]

When I open the CrossCorrelation.VI there's a possibility to choose between time and frequency domain. Does that mean that if I choose time domain, the cross correlation is calculatet by the sum-formula and if I choose frequency domain by computing the FFT, multiplying and Inverse FFT?

Thanks

Yes, I think you are correct. I did a few basic tests, and (very small) rounding errors are apparent in the frequency domain method, which don't appear in the time domain method.
