Extremwertbestimmung mit VI "Peak Detection"

Auch schon mal weiter runter in der Hilfe gescrollt:

Zitat:Peak Detector Details
The data set can be passed to the Peak Detector VI as a single array or as consecutive blocks of data.

This Peak Detector VI is based on an algorithm that fits a quadratic polynomial to sequential groups of data points. The number of data points used in the fit is specified by width.

For each peak or valley, the quadratic fit is tested against the threshold. Peaks with heights lower than the threshold or valleys with troughs higher than the threshold are ignored. Peaks and valleys are detected only after the VI processes approximately width/2 data points beyond the location of the peak or valley. This delay has implications only for real-time processing.

The Peak Detector VI must be notified when the first and last blocks are passed into the VI, so that the VI can initialize and then release data internal to the peak detection algorithm.
