How does peak detection algorithm work?
The algorithm compares each point to the average of the preceding lag points. However, when calculating this average, we adjust the values for any points that are considered to be a peak, because otherwise, they will distort what we want to see as the moving baseline.
How do you find a peak in a signal?
A common requirement in scientific data processing is to detect peaks in a signal and to measure their positions, heights, widths, and/or areas. One way to do this is to make use of the fact that the first derivative of a peak has a downward-going zero-crossing at the peak maximum.
