Hi All, This should be a simple question. I have the following:
sdr -> decimation/filters -> stream to vector -> FFT -> complex to mag2 -> log10 -> python block - > ... The FFT block is configured as: type: complex Direction: Forward Shift: yes length: equal to input vector length The python block should be trivial in that it just snips out a subset of the FFT bins (around the center frequency). My assumption was that the center frequency is at the middle bin (Shift = True) and that if I want +/- 500Hz (for example) I can just take the bins (middle bin index - 500) -> (middle bin index + 500) However that does not seem correct. Perhaps there is a bug somewhere else but just wanted to check Im doing the right thing.
