The calculation of the integral occurs using the trapezoid formula, i.e. with N equal to the number of values, I[0] = 0 applies to the left edge, and for all other values, I[n] = I[n-1] + (X[n] – X[n-1]) * (Y[n] + Y[n-1]) / 2 applies.
If you want to calculate the local extrema of a signal you can use the event isolation analysis object. Calculate the indices of the local extrema and use the index operator to extract the values between the peaks.
