2D-FFT Block Correctly A pplies D ivide-By-Two on
Butterfly Outputs
The Skip divide-by-two on butterfly outpu ts for fixed-poi nt signals check
box on the Fixed-point pane of the 2D-FFT block dialog has been moved
to the Main pane a nd renamed Divide butterfly outputs by two.This
check box now correctly applies to both fixed -p oint a nd fl oating-point inp uts.
In releases prior to R2008b, the block a lways ignored this check box for
floating-point inputs.
Compatibility Considerations
The 2D-FFT block can give results in R2008b and later releases that are scaled
differently than in p revio us releases when all the following conditions are met:
1 T he block input is floating point.
2 The Divide butterfly ou tputs by two check box is sele cted (or the Skip
divide-by-two on butterfly outputs for fixed-point signals check box on
the ‘Fixed-point’ pane was NOT selected, for releases prior to R2008b)
