Filtering Motion Data in Python by Maximum Position for each Time Period I am trying to filter data points by time and position in python so that only the highest position for each second of time is left in the data set. So here is the situation, I used a motion sensor to record the oscillations of a spring/mass system and I am trying to do an exponential curve fit of the damping. The highest position decreases over time, and the periods last about a second. I thought maybe if I turned the times into integers then I could get rid of everything except the max...
