This vi takes the input data and decimation factor and the output is the decimated array. But don't we need an anti-aliasing filter before the decimation operation? Does the vi have a filter inside it?
Thank so much for the reply but I still don't understand exactly what it is doing.
If averaging is false, then the new samples of the decimated array are multiplied by the decimation factor
if averaging is true, then the new samples of the decimated array are averaged by the decimation factor, but why every time there is the summation of k values for each i.
