-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Jordan,
you have to be aware that WAVs are only meant to hold real-valued data. So the question stands: how to "store" complex signals in WAVs? Usually, this is done by mapping the real and imaginary parts to the two stereo channels. Since I don't know what the programs you mention expect, I can't really help you diagnose that. So: What does your "complex>real" stage look like? If the GNU Radio WAV source tells you that there are no samples, chances are good that the file is empty, and something in your signal generation went wrong. If you generate a well known complex signal in GRC and output it (the same way as you intend to do it for sdr#) to a wave file, can you then open that file in software such as audacity? I don't quite see what you mean with "FFT attached to the complex > float stage". FFT is something you usually do to complex vectors, not only to the real/imag parts isolated. Looking forward to hearing from you, Marcus On 28.01.2014 00:35, Jordan Johnson wrote: > Long time reader, first time poster so hopefully I'm doing this > whole mailing list thing right. > > I was hoping someone could point me in a direction towards fixing > this odd problem I am having.
