Applies a median filter of rank to a signal.
Rank is right rank if right rank is greater than zero. Rank is left rank if right rank is less than zero.
A Boolean that specifies the initialization of the internal state of the node.
True | Initializes the internal state to zero. |
False | Initializes the internal state to the final state from the previous call of this node. |
This node automatically initializes the internal state to zero on the first call and runs continuously until this input is True.
This input is available only if you wire a double-precision, floating-point number to signal.
Default: False
Input signal to filter.
This input accepts the following data types:
If you wire an array or waveform to signal, the number of elements, n, in signal must be greater than right rank. If the number of elements in signal is less than or equal to right rank, the node sets filtered signal to an empty array and returns an error.
Number of elements used to compute the median filter to the left side.
left rank must be greater than or equal to 0.
Default: 2
Number of elements used to compute the median filter to the right side.
If right rank is less than 0, the node assumes right rank is equal to left rank. right rank must be less than the number of elements in signal.
Default: -1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Error information.
The node produces this output according to standard error behavior.

This node obtains the elements of filtered signal using the following equation.

The following equation describes J _{ i }.
where rl is the filter left rank, and rr is the filter right rank.
The following illustration shows the computation of Y _{ i }.
