Mathematics and Electronics a continuous function (defining a ramp, sense 6) whose value increases linearly for a particular range of values of the independent variable, and is constant outside this range; spec. the function f(x) = x + ?x?/ 2, which is zero for negative values of the argument and is linear with a gradient of 1 for positive values.

IRE 41 660 The driving force rises to the final value in a finite time rather than in zero time. This driving force will be called a ‘ramp function’. 1963 F. S. Grodins Control Theory & Biol. Syst. viii. 163 The forcing in Eq. (8.24) during this interval is the sum of a ramp function and a step function. 2000 D. S. Levine Introd. Neural & Cognitive Modeling (ed. 2) v. 189 The functions f and g..can either be sigmoids or ramp functions, that is, linear above some threshold and 0 below the threshold. < as lemmas |
