Description[edit]
a signal is a codified message, that is, the sequence of states in a communication channel that encodes a message. noise can refer to any random fluctuations of data that hinders perception of an expected signal. Signal and Noise - antonym (Q131779) --Fractaler (talk) 07:06, 21 December 2016 (UTC)
- Yes, but this was explicitly just audio noise, not noise in the sense of signal and noise. noise (Q11306265) would be the opposite. Sänger (talk) 15:34, 21 December 2016 (UTC)
- Now description: "varying physical quantity that conveys information", no "audio". noise (Q11306265) (set) - random electrical signal. noise (Q179448) (superset for Q11306265) - random fluctuations of data that hinders perception of an expected signal. --Fractaler (talk) 17:55, 21 December 2016 (UTC)
- So the german and english definitions of Geräusch (noise (Q179448)) don't fit, in german it's just Sammelbegriff für alle Hörempfindungen, die nicht als Ton, Klang, Tongemisch, Zusammenklang oder Klanggemisch bezeichnet werden können, only audio, no real data (i.e. data only in the sense that everything is/contains data).
