Re: Time error between two waveforms

Hello C. Allen Weekley, Thank you for contacting National Instruments. Will you please elaborate on what you mean by RMS error calculation for the time axis? Are you looking for the phase shift? When you subtract two waveforms, you are calculating the difference between two amplitudes at a

Sean, Thank you for the reply. I should go back to my client to see if they can give me a more specific definition, but the approach I thought of was as you described, subtracting the difference in times at the same amplitude. But, one problem is that there could be many places where the

Time error between two waveforms

If I subtract two waveforms and feed the resulting difference waveform into an RMS function, I get the RMS of the amplitude errors between the two waveforms. A smilar RMS error calculation for the time axis is required. Is there an existing function that would do this, or how would I approach
