Filtering and Interpolation

The filtering and interpolation stage of the OSP block increases the effective sample rate of the signal generator while protecting the frequency spectrum of the interpolated data from images. This protection occurs when the data passes through a lowpass filter after zero stuffing. The frequency response of the low pass filter can be changed with the Filter Type property or the NIFGEN_ATTR_OSP_FIR_FILTER_TYPE attribute.
