IC89789: NOISY DATA IN SPECTRUM OUTPUT FROM FFT OPERATOR FOR LARGE DATA SETS
Fixes are available
Closed as program error.
When you have an SPL application that uses an FFT operator and the algorithm parameter is set to complexFFT, realFFT, inverseRealFFT, or inverseComplexFFT, noisy data or unwanted artifacts are visible in the output spectrum. This problem is more likely to occur when the input data set is large. The problem does not occur when the algorithm parameter is set to realDFT.
You can work around the problem by setting the algorithm parameter to realDFT, but this algorithm has less accurate results, particularly when compared to complexFFT and inverseComplexFFT.
See Error Description.
This problem is fixed in Version 3.0 Fix Pack 1 and later fix packs.
