WebBut in classical and quantum mechanics (i.e., in most of physics), time is treated as continuous. Physics would become very awkward if expressed in terms of a discrete time: The discrete case is essentially untractable since analysis (the tool created by Newton, in a sense the father of modern physics) can no longer be applied.

WebBasic Definitions. A continuous-time (CT) signal is a function, s ( t ), that is defined for all time t contained in some interval on the real line. For historical reasons, CT signals are often called analog signals. If the domain of definition for s ( t) is restricted to a set of discrete points tn = nT, where n is an integer and T is the ... In mathematical dynamics, discrete time and continuous time are two alternative frameworks within which variables that evolve over time are modeled. See more Discrete time views values of variables as occurring at distinct, separate "points in time", or equivalently as being unchanged throughout each non-zero region of time ("time period")—that is, time is viewed as a discrete variable. … See more A variable measured in discrete time can be plotted as a step function, in which each time period is given a region on the horizontal axis of … See more In contrast, continuous time views variables as having a particular value only for an infinitesimally short amount of time. Between any two points in time there are an See more Discrete time is often employed when empirical measurements are involved, because normally it is only possible to measure variables … See more • Aliasing • Bernoulli process • Digital data • Discrete calculus See more

WebIn continuous-time dynamics, the variable time is treated as continuous, and the equation describing the evolution of some variable over time is a differential equation.
