Filters a signal using a lowpass FIR filter with equi-ripple characteristics. Lowpass filters pass low frequencies and attenuate high 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.
The frequency of the passband. passband frequency must be greater than zero and observe the Nyquist criterion.
The frequency of the stopband. stopband frequency must be greater than passband frequency and observe the Nyquist criterion.
Number of taps in the FIR filter.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The sampling frequency in Hz.
sampling frequency is available only if you wire a 1D or 2D array of double-precision, floating-point numbers to signal. The value must be greater than zero.
Default: 1, which is the normalized sampling frequency
Result of filtering the input signal.
Error information. The node produces this output according to standard error behavior.
The passband of the filter goes from zero frequency to the passband frequency. The transition band goes from the passband frequency to the stopband frequency. The stopband goes from the stopband frequency to the Nyquist frequency.
