non-lineˈarity [non- 1.] The property of not being linear; esp. lack of proportionality between two related quantities (as input and output).
1929Physical Rev. XXXIII. 633 (heading) Non-linearity of photoelectric response near long wave-length limit. 1937J. Orr tr. Iordan's Introd. Romance Linguistics iv. 379 Non-linearity of structure is shown to be present when a sign ‘cumulates’ more than one function. 1948Proc. IRE XXXVI. 37/1 Any transmission system containing vacuum tubes is more or less nonlinear, with the degree of nonlinearity increasing with increasing signal level. 1965Math. in Biol. & Med. (Med. Res. Council) vi. 266 In some cases, such as an excessively branching syncytial network, the gross non-linearities may be completely smoothed out and virtually linear polarizing current-voltage relations could then be obtained. 1967Oceanogr. & Marine Biol. V. 30 Part of the non-linearity in the latter equations arises from the assumption that the bottom friction is proportional to the square of the bottom current. 1973Sci. Amer. July 29/3 The presence of such nonlinearity in the control characteristics gives rise to additional frequencies at double, triple and quadruple the frequency of the basic oscillation. |
