    Hello all,
    with two formulas i calculate the upper and lower envelopes.
    Both envelopes have X-axis from 0-60 sec, but different number of values ??(372 and 349 points).
    In a other formula I subtract (UpperEnvelope – Lower Envelope)
    Surprisingly, this result has only a length of 0-55sec and 349 points.

    Why do I lose this data, respectively 5sec of time?
    How can I force the calculation to consider all points?

    Thank you for your feedback

    You have to resample one of your signals using the Sample-function.
    Example:
    1. formula Upper: UpperEnvelope(Signal)
    2. formula Lower: LowerEnvelope(Signal)
    3. formula Diff: Upper – Sample(Lower, Upper.x)
