ramallo Posted November 26, 2013 Report Share Posted November 26, 2013 I don't think the zfr has aes out. Are you confusing frequency responce with sample rate? The qrx operates it's aes output at a sample rate of 32khz because of processing power limitations. No, according to Nyquist you the highest frequency you can get is the half of the sampling frequency. 32 kHz is the double of 16kHz. I know that the FZR don't have AES/EBU, was just an example (of the above) Quote Link to comment Share on other sites More sharing options...

" you are misquoting Dr. Nyquist... according to Nyquist the highest frequency you can get is less than half of the sampling frequency. ...and he does not say exactly how much less, but there are also the technical considerations...

You'r right, in the real world is less than a half. http://en.wikipedia.org/wiki/Nyquist_rate http://en.wikipedia.org/wiki/Nyquist_frequency Quote Link to comment Share on other sites More sharing options...

It's only the qrx aes output that runs at 32khz. Quote Link to comment Share on other sites More sharing options...

Yes, all of this devices have in his technical specs 48kHz 24 bit "converters", but apart of the FZR the transmitters are also band limited (16kHz), this suggest me that all of this devices works at 32kHz (Almost in the final part of his signal processing).
