Name
Downsample -- reduce sample rate by discarding samples
Synopsis
downsample [factor(2)]
Function
Downsample the signal by an integer factor: Only the first out of each factor samples is retained, the others are discarded.

No decimation filter is applied. If the input is not a properly bandlimited baseband signal, aliasing will occur. This may be desirable, e.g., for frequency translation.

For a general resampling effect with anti-aliasing, see rate. See also upsample.
