# Decimation
Component Type: Processor (Subcategory: Basic Math)
The decimation operation performed by this component consists in an anti-aliasing low band pass filter plus a down-sampling. The component outputs a computed sample after receiving a certain number of input samples according to the down-sampling-ratio property value. So the resultant signal is like the original signal, but sampled to a lower ratio determined by the mentioned property.

# Input Port Description
- input [double]: Input port for the signal to be decimated.
# Output Port Description
- output [double]: Output port of the decimated signal.
# Properties
- DownSamplingRatio [integer]: Defines the ratio between the number of samples in the input and output ports.
