The LabView VI employs simple array manipulation and uses a “for” loop. ... you use the “rotate-1D-array-block” case structure to flip the array if the ending frequency is lower than the starting ...

To normalize the start and stop frequencies, you must change the unit to cycles per sample. Do that by dividing the Fstart and Fstop frequencies in Hertz by the sample rate. A good rule of thumb is to ...
