Decimator downsamples the input signal by an integer factor. Downsampling is achieved by sending only every nth input sample to the output. There are two ways of setting the degree of downsampling, either using the MULTIPLE parameter or using the OUTPUT_RATE parameter. Only one of these should be set. Using MULTIPLE directly sets the factor by which to downsample i.e. if it is set to 3 then every 3rd sample will be passed to the output. Alternatively, using OUTPUT_RATE sets the desired output rate. In this case, an integer downsampling factor will be selected automatically so that the actual output sample rate matches the desired rate as closely as possible.
|Inputs||Meaning||Sample||1-D frame||2-D frame|
|out1||data at lower sampling rate|
|MULTIPLE||Integer||-||The decimation factor|
|OUTPUT_RATE||Float||-||The desired output rate|
