Hi,

   

 

   

has anyone used the CMSIS-DSP RFFT_Q15 implementation yet? Currently I'm feeding it with predefined values to check if I understand it correctly, but the output has negative values for the frequency bins, and I don't know why. For my understanding the output should be only positive values.

   

 

   

Regards,
