Filters a signal using a highpass FIR filter with equi-ripple characteristics. Highpass filters pass high frequencies and attenuate low frequencies.
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
The frequency of the passband. passband frequency must be greater than stopband frequency and observe the Nyquist criterion.
Default: 0.25
The frequency of the stopband. stopband frequency must be greater than zero and observe the Nyquist criterion.
Default: 0.2
Number of taps in the FIR filter.
Default: 33
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
Sampling frequency in Hz. sampling frequency must be greater than zero.
This input is available only if you wire one of the following data types to signal:
Default: 1, which is the normalized sampling frequency
Error information.
