Network Switches

No, I would just say you are a bit slower in the UK .....

Would you rather I said encoding of the baseband signal into digital and decoding of the baseband signal into audio instead of ADC and DAC? The baseband signal will be encoded once with an ADC in a studio these days.

After that it is all digital. It should have been pretty obvious from what I wrote that that is what I meant." In the distribution of a single radio programme, for instance, it will go through a number of ADCs and DACs for technical reasons before it is even sent back from the cloud for final distribution" ... I can assume you mean encoded digital data, not baseband encoding and decoding, which in the context of this whole discussion is, well, rather meaningless and pedantic without being useful as the parameters for noise rejection, data recovery, etc. are 1) completely different from baseband audio, and 2) not really even the point of most of this discussion.

Last, if you are going to be pedantic, you may want to figure out who your audience is.


Studios crept into the discussion because someone tried to use, erroneously, that "professionals", i.e. in radio and TV studios don’t care about this.

Ah I think I get it now.
You are saying that adding an extra piece of equipment, a switch or anything , is adding further potential to add noise to your audio system. Nothing to do with the digital audio it is switching.

Yes, that is the perspective I'm engaging on here.  Therefore, as it applies to network switches I'm mainly interested in the noise reduction they are applying to the power supplies for example as a potential source of noise and unrelated to the digital signal.  I see many of the models that the OP provided at the beginning of thread did include measures to reduce EM/RF noise but for now I don't think those incremental gains justify the costs - at least not in my realm of budgets and a value proposition.

Hey atdavid !

Guglielmo Marconi called.

He wants his 'modern techniques in communications' handbook back
