An introduction to Markov chains
web.math.ku.dkmodels for random events namely the class of Markov chains on a finite or countable state space. The state space is the set of possible values for the observations. Thus, for the example above the state space consists of two states: ill and ok. Below you will find an ex-ample of a Markov chain on a countably infinite state space, but first
0.1 Markov Chains - Stanford University
web.stanford.eduSince the state space is countable (or even finite) it customary (but not always the case) to use the integers Z or a subset such as Z + (non-negative integers), the natural numbers N = {1,2,3,···} or {0,1,2,··· ,m} as the state space. The specific Markov chain under consideration often determines the natural notation for the state space.

A discrete-time stochastic process {X n: n ≥ 0} on a countable set S is a collection of S-valued random variables defined on a probability space (Ω,F,P).The Pis a probability measure on a family of events F (a σ-field) in an event-space Ω.1 The set Sis the state space of the process, and the

core.ac.ukDiscontinuous Conduction Mode occurs due to low load current operation of converters which employ current or voltage unidirectional switches. The switching ripples in inductor current or capacitor voltage causes the polarity to reverse of the applied switch current or voltage and thus a zero current mode is reached.
