Dictionary:Resample
To change the sampling frequency (or the interval between adjacent samples). To decrease the number of samples is to decimate; for example, a data set at 2 ms intervals can be ‘‘decimated’’ to a data set at 4 ms intervals by dropping every other sample. To increase the number of samples is to reconstitute; for example, to obtain samples interpolated between the values of a data set at 2 ms intervals to yield a data set at 1 ms intervals.
