I would like to ask you which algorithm is used for peak integration in Clarity? Is it any numeric integration like Simpson method or trapezoid?

Our A/D boards use δΣ (Delta-Sigma) converters- with continuous integration, which provide partial integrals for each sampling interval. The cumulated values for integrated signal are given at equidistant time intervals given by sampling frequency, thus the area of the integrated peak is calculated as a sum of the areas for those time intervals according to formula
∫f(t) = ∑(f(t) + f(t + ∆t))/2*∆t

Thank you Ivan for your reply. It's clear for me now. It's like trapezoidal rule.
