		As the time changes in discrete ticks, the system evolves in a sequence of discrete jumps through its phase space, one jump (which may or may not be large) per atomic tick.
		Their supposed discreteness stems not from quantum level spacings, but from their inability to distinguish between two too close levels due to inherent system noise, whether brownian/quantum, or from external source.
		Some Actual Systems and Their (Hypothetical) Hamiltonians In biological systems, the signal propagation velocity is significantly slower, being about 120 m/s for saltatoric propagation of myelinized (Swann cell) mammal axons, being but a tiny (4*10^-7) fraction of of the light propagation velocity in vacuum.

	CTM: Digital control Tutorial
		The basic difference between these controllers is that the digital system operates on discrete signals (or samples of the sensed signal) rather than on continuous signals.
		For instance, a system is unstable when any pole is located to the right of the imaginary axis.
		The system is stable when all poles are located inside the unit circle and unstable when any pole is located outside.

		The real system, regarded as a source of behavioral data, is some part of the real world of interest.
		Discrete event models which use continuous state and continuous time axis differ from continuous models by the fact that only a finite number of state changes may occur within finite time interval depending on instantaneous "events".
		The discrete event system is driven by events, and a typical example of discrete system is a queueing system shown as Figure 2.

	Hybrid and Discrete Event Dynamic Systems for Robotic Observation
		The underlying mathematical representation of complex computer-controlled systems is still insufficient to create a set of models which accurately captures the dynamics of the systems over the entire range of system operation.
		We suggest the use of a representation of discrete event dynamic systems, which is augmented by the use of a concrete definition for the events that causes state transitions, within the observation domain.
		Dynamic systems are sometimes modeled by finite state automata with partially observable events together with a mechanism for enabling and disabling a subset of state transitions [11,13,14], the reader is referred to those references for more information about this class of DEDS representation.

		The sample time of a discrete signal can refer either to the period of samples taken from that signal or to the time that a particular sample was taken.
		In the first case, it is the inverse of the sample rate.
		When converting from analog to digital, the analog signal must usually be sampled -- that is, measured or read -- at discrete intervals of time.

		A few simple heuristics have guided the development of Digital Philosophy: simplicity, economy, and Occam’s Razor [1]. In particular, Digital Philosophy is a totally atomic system. Everything fundamental is assumed to be atomic or discrete and, thereby, so is everything else.
		Automata Theory and its variants are the mathematics of fundamental processes in DP because they have the property of allowing for exact, dynamic models of discrete temporal processes.
		The principle is also expressed "Entities are not to be multiplied beyond necessity."
