Digital And Analogue Cables


I'm confused as to why USB, HDMI, Coax cables are referred to as digital  and RCA as analogue cables.

All of the cables transmitt voltage variation through the wires, so how are they  digital and the other analogue? 

Can someone shed some light on it without manufacturer marketing lingo.

@Op I may be simplifying too much.

Analog cables

  • Speaker cables
  • Interconnects - RCAs or XLRs carrying analog signals between components (analog outputs from a DAC, phono stage, preamp)

Digital cables move digital signals - I have a network player/preamp so it’s all in one box. And many folks have separate components for streamer, DAC, Clock and music libraries connected using digital connections.

  • This is where I think it gets confusing because there are a variety of USB, Optical, Coaxial, HDMI, AES and I’m sure there are others
