signal function
61Periodic function — Not to be confused with periodic mapping, a mapping whose nth iterate is the identity (see periodic point). In mathematics, a periodic function is a function that repeats its values in regular intervals or periods. The most important examples are …
62Lambert W function — The graph of W(x) for W > −4 and x < 6. The upper branch with W ≥ −1 is the function W0 (principal branch), the lower branch with W ≤ −1 is the function W−1. In mathematics, the Lambert W function, also called the Omega function or product… …
63Citation signal — Introductory signals are used in legal citations to present authorities and show how the authorities relate to propositions in textual statements. A legal writer uses an introductory signal to tell readers how her citation to legal authority… …
64Video signal generator — A video signal generator is a type of signal generator which outputs predetermined video and/or television waveforms, and other signals used to stimulate faults in, or aid in parametric measurements of, television and video systems. There are… …
65Traffic signal preemption — is a type of system that allows the normal operation of traffic lights to be preempted, often to assist emergency vehicles.[1][2] The most common use of these systems is to manipulate traffic signals in the path of an emergency vehicle, stopping… …
66Step function — In mathematics, a function on the real numbers is called a step function (or staircase function) if it can be written as a finite linear combination of indicator functions of intervals. Informally speaking, a step function is a piecewise constant …
67Gaussian function — In mathematics, a Gaussian function (named after Carl Friedrich Gauss) is a function of the form::f(x) = a e^{ { (x b)^2 over 2 c^2 } }for some real constants a > 0, b , c > 0, and e ≈ 2.718281828 (Euler s number).The graph of a Gaussian is a… …
68Sinc function — In mathematics, the sinc function, denoted by scriptstylemathrm{sinc}(x), and sometimes as scriptstylemathrm{Sa}(x),, has two definitions, sometimes distinguished as the normalized sinc function and unnormalized sinc function. In digital signal… …
69Aviation Section, U.S. Signal Corps — The Aviation Section, U.S. Signal Corps, was the name of the military aviation service of the United States Army from 1914 to 1918, and a direct ancestor of the United States Air Force. It replaced the Aeronautical Division, U.S. Signal Corps and …
70Stretched exponential function — Figure 1. Illustration of a stretched exponential fit (with β=0.52) to an empirical master curve. For comparison, a least squares single and a double exponential fit are also shown. The data are rotational anisotropy of anthracene in… …
