Continuous and Discrete System Models

Continuous-time and discrete-time systems are two common ways to model signals and their outputs. In continuous-time systems, both input and output signals change smoothly as time moves continuously. These systems are often written with differential or algebraic equations.

Continuous-time systems have continuous input and output signals, with time measured continuously, and are generally defined by differential or algebraic equations.

For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived using Ohm's law and the capacit...
