block exponent in FFT core

[Altera_Forum]

One question regarding the block exponent in FFT core. 

 I have set up a 8192 sample FFT engine using the FFT ip core. Now, does the same source exponent apply to EACH of the output FFT values? As in, does the output block of 8192 FFT samples share the SAME exponent for each of the 8192 output values? or can it vary for each of those?

Yes, the exponent applies to all the samples of one transform. 

See Figure 3-4 of the user guide for example.  Jérôme
