signal function
41Bessel function — In mathematics, Bessel functions, first defined by the mathematician Daniel Bernoulli and generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel s differential equation: for an arbitrary real or complex number α (the order of the …
42Closed-loop transfer function — A closed loop transfer function in control theory is a mathematical expression (algorithm) describing the net result of the effects of a closed (feedback) loop on the input signal to the circuits enclosed by the loop. Contents 1 Overview 2… …
43Coherence (signal processing) — Contents 1 Background 2 Definition and Formulation 3 Example 4 Extension to non stationary signals 5 …
44Analytic function — This article is about both real and complex analytic functions. The article holomorphic function is solely about analytic functions in complex analysis. An analytic signal is a signal with no negative frequency components. In mathematics, an… …
45Heaviside step function — The Heaviside step function, H , also called the unit step function, is a discontinuous function whose value is zero for negative argument and one for positive argument.It seldom matters what value is used for H (0), since H is mostly used as a… …
46Triangular function — The triangular function (also known as the triangle function, hat function, or tent function) is defined either as::egin{align}operatorname{tri}(t) = and (t) quad overset{underset{mathrm{def{{=} max(1 |t|, 0) = egin{cases}1 |t|, |t| < 1 ,… …
47Digital signal processor — A Digital Signal Processor chip found in a guitar effects unit. A digital signal processor (DSP) is a specialized microprocessor with an architecture optimized for the fast operational needs of digital signal processing.[1] …
48Mixed-signal integrated circuit — A mixed signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. [1] [2] [3] Contents 1 Examples 2 …
49Continuous signal — A continuous signal or a continuous time signal is a varying quantity (a signal) whose domain, which is often time, is a continuum (e.g., a connected interval of the reals). That is, the function s domain is an uncountable set. The function… …
50Optical transfer function — The optical transfer function (OTF) of an imaging system (camera, video system, microscope etc) is the true measure of resolution (image sharpness) that the system is capable of. The common practice of defining resolution in terms of pixel count… …
