I have a waveform (1D array of SGL) that I need to lowpass filter. When
I use the Butterworth VI, I can set the sample frequency with which to
sample & vary the cutoff freuqency & observe the low-pass
filtering results.
When I use the digital IIR filter VI, it gves me the error :
Analysis: The following conditions must be met: 0 < f_low <= f_high <= fs/2.
How does it know what the sampling frequency is ?
IS there a setting in the IIR filter specifications cluster that will help ?
