| Inspect fixed point FFT |
 Choose "Scale 10x" in View menu.  The imaginary-part (green) is about 15,000 at the peak.  In FFT with floating point, the magnitude of the input was 1.0 and the
spectrum was about 500. The same relationship occurs in fixed point, too.
The input is 32 and the spectrum is about 500 times bigger.
