`Decimate`¶

Decimate (subsample) the signal by an integer factor.

This filter implements no anti-aliasing filter -- that is, you need to precede this filter by a low-pass filter (e.g., FIR or IIR) which cuts out below half of the new sampling rate. Important: If no anti-aliasing filter is used, then frequency content above the new sampling rate will be mirrored and appear as additional noise in the resampled signal. If this filter is ran along the time axis, it will maintain an internal state to ensure that every k'th sample is picked even across chunk boundaries. Version 1.0.1

Ports/Properties¶

`data`¶

Data to process.

verbose name: Data
default value: None
port type: DataPort
value type: Packet (can be None)
data direction: INOUT

`factor`¶

Decimation factor. Only every k'th data value will be transferred into the output.

verbose name: Decimate By Factor
default value: 2
port type: IntPort
value type: int (can be None)

`axis`¶

Axis along which to decimate.

verbose name: Decimate Along Axis
default value: time
port type: ComboPort
value type: str (can be None)

`set_breakpoint`¶

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

verbose name: Set Breakpoint (Debug Only)
default value: False
port type: BoolPort
value type: bool (can be None)

`metadata`¶

User-definable meta-data associated with the node. Usually reserved for technical purposes.

verbose name: Metadata
default value: {}
port type: DictPort
value type: dict (can be None)
