An '''Electronic System''' is a physical interconnection of components, or parts, that gathers various amounts of information together. It does this with the aid of input devices such as sensors, that respond in some way to this information and then uses electrical energy in the form of an output action to control a physical process or perform some type of mathematical operation on the signal. But electronic control systems can also be regarded as a process that transforms one signal into another so as to give the desired system response. Then we can say that a simple electronic system consists of an input, a process, and an output with the input variable to the system and the output variable from the system both being signals. There are many ways to represent a system, for example: mathematically, descriptively, pictorially or schematically. Electronic systems are generally represented schematically as a series of interconnected blocks and signals with each block having its own set of inputs and outputs. As a result, even the most complex of electronic control systems can be represented by a combination of simple blocks, with each block containing or representing an individual component or complete sub-system. The representing of an electronic system or process control system as a number of interconnected blocks or boxes is known commonly as “block-diagram representation”.<ref>Definition - What is an Electronic System [https://www.electronics-tutorials.ws/systems/electronic-system.html Tutorials]</ref>

 *Continuous system: Continuous system is that in which the input signals are defined as the analog signals. The analog signals are continuous in nature, so they are called as “continuous time signals”. The magnitude of the continuous signal will vary with the time period T. As the input is Analogues in nature, the continuous electronic systems produce the analogous output. This is the reason they are notified as “Pure analog systems”. The values of the continuous electronic system varies only with time.

 *Discrete system: The discrete system is defined as the system having the sequence of discrete time values as its input. The values obtained at particular intervals of time are called “Discrete values”. As the input of discrete system is the sequence of instinctual values, the output will be in the form of sequence of numbers. So these discrete systems are also known as “Digital systems”. Generally the output of digital system will be a binary number sequence, such as the collection of 0’s and 1’s. One important thing about the discrete system is that, the discrete values defined at particular time intervals must be spaced equally. For example, if the time periods are t1, t2, t3, t4 and t5, then t1 – t2 = t2 – t3 = t3 – t4 = t4 – t5. The values of discrete system don’t vary over the time period, but changes at particular instances of time.

 ''Representing continuous system as a set of discrete intervals''
 We can represent the continuous electronic system into discrete electronic system, by changing the domain of the system. This means, a continuous system with input and output signals as X (t) and Y (t) can be represented as discrete electronic system with input and output as X (n) and Y (t), where X (t) and Y (t) represents the time domain and X (n) and Y (n) represents the frequency domain
