Calculates continuous AC, DC, and RMS values of a signal. This node gives simpler control over the individual AC, DC, and RMS calculations than the AC DC and RMS (Continuous) node.
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.
Default: False
Type of averaging to apply to the signal.
Name | Description |
---|---|
Linear | Applies linear averaging to the signal. |
Exponential | Applies exponential averaging to the signal. |
Default: Linear
Type of window to apply to the signal when you use linear averaging.
Windowing can help increase measurement accuracy for signals that are dominated by periodic components.
Name | Description |
---|---|
Rectangular (none) | Does not apply a window. |
Hanning | Applies a Hanning window. |
Low side lobe | Applies a low side lobe window. |
Default: Rectangular (none)
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
DC value of the signal.
This output can return a double-precision, floating-point number or a 1D array of double-precision, floating-point numbers.
Root mean square value of the signal.
This output can return a double-precision, floating-point number or a 1D array of double-precision, floating-point numbers.
Error information.
The node produces this output according to standard error behavior.
