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

Example:
1. formula Upper: UpperEnvelope(Signal)
2. formula Lower: LowerEnvelope(Signal)
3. formula Diff: Upper – Sample(Lower, Upper.x) -
