Median filtering is performed by sliding a window (an interval of a number of consecutive data points) over the data time series. For each time window, the central value of the interval is replaced by the median value in the interval: the middle value of the interval after sorting the values in the interval in ascending order.
Next, select a data channel and the interval half width n (each data window will consist of the n values before and after the central data point).
Then, press the
Run button to start the filtering process.
The values of the selected channel will be replaced in the database by
the smoothed values.
Caution: this operation is irreversible!
