[Flexradio] Filter in new FFTW3 code

2006-02-04 Thread Edson Pereira
I am testing the new FFTW3 DttSP core windows port made by John and a development version I have received from Frank and Bob and am noticing that the filtering is not as sharp as before in the FFTW2 code. I wander if the difference is related to the size of the FFT used (512 now x 2048 before).

[Flexradio] Impulse Response

Hello: I will ask this here before diving deep into the DSP books. :-) Given the SDR-1000 impulse response using the internal pulse generator, how could one use the results (a complex FFT) for correcting the IQ phase and magnitude errors in the frequency domain? 73, -- Edson
