What is a real-valued signal? Are there any other kinds of signals? - Abdull ( talk) 15:33, 7 February 2010 (UTC)
"Real-valued signals have Fourier spectra with symmetry about zero. " more precisely should be: "Real-valued signals have Fourier transforms that are conjugate symmetric about zero. [1] Twarner250 ( talk) 21:41, 11 March 2020 (UTC)

"See aliasing for a simpler formulation of this Nyquist criterion that specifies the lower bound on sampling rate (but is incomplete because it does not specify the gaps above that bound, in which aliasing will occur)"

Undersampling is a term used in many different contexts. This article refers specifically to audio (not statistical sampling or other contexts). Should it possibly be given a more specific title? — Preceding unsigned comment added by Mcsmom ( talk • contribs) 16:20, 25 November 2017 (UTC)
