Detect the peak of a signal.

If a peak is detected, this block outputs a 1, else it outputs 0's.


(R): Run-time adjustable

TH factor rise (R)
Determines when a peak has started. An average of the signal is calculated and when the value of the signal goes over threshold_factor_rise*average, we start looking for a peak.
TH factor fall (R)
Determines when a peak has ended. An average of the signal is calculated and when the value of the signal goes below threshold_factor_fall*average, we stop looking for a peak.
Look ahead (R)
Used when the threshold is found to look if there another peak within this step range. If there is a larger value, we set that as the peak and look ahead again. This is continued until the highest point is found with this look-ahead range.
Alpha (R)
The gain value of a moving average filter

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
