Discrete time series and continuous time series

Discrete Time Series: A time series is discrete when observations are taken only at specific times. The term discrete is used for series of this type even when the measured variables is a continuous variable. Continuous Time series: A time series is continuous when observations are made continuously through time.

What is the difference between discrete and continuous time?

A primary difference between discrete-time and continuous-time models is that the latter take into account the exact time interval between measurements while the former do not—discrete-time models assume equally spaced time-intervals.

What is the difference between continuous and discrete model?

Discrete model: the state variables change only at a countable number of points in time. These points in time are the ones at which the event occurs/change in state. Continuous: the state variables change in a continuous way, and not abruptly from one state to another (infinite number of states).

Is time continuous or discrete series?

Between any two points in time there are an infinite number of other points in time. The variable "time" ranges over the entire real number line, or depending on the context, over some subset of it such as the non-negative reals. Thus time is viewed as a continuous variable.
