[Discuss-gnuradio] shift param in FFT block in GRC

2012-06-12 Thread John Shields
When I add a FFT block in the GRC (gr_fft_vxx if I understand things correctly) I am offered a boolean parameter 'shift'. When I attempt to discern the code, there is a comment: // apply a fft shift on the data - for the fwd FFT and // apply an ifft shift on the data - for reverse. Wha
