FIR Filter
NI-FGEN includes a number of built-in lowpass pulse-shaping filters. NI-FGEN calculates the coefficients for each filter. Because the coefficients are scaled for unity-gain, the filters may overflow if transients (such as step response) are presented at the filter input. Use the Filter Type property or the NIFGEN_ATTR_OSP_FIR_FILTER_TYPE attribute to set the FIR filter type. The following filters are currently available:
