The study of systems in analysing and handling signals is said to be as Signals and Systems. In other words, it is used to perform different operations on signals like acquisition, sampling, convolution, analysis, type conversion, etc. At the same time, it also focuses on different types of systems. This article is intended to provide useful information like emerging research areas, topics in embedded systems, techniques, toolboxes, etc. on Signals and Systems Projects using Matlab!!!

Signal processing techniques used in various systems have the key player role in analyzing signal characterization. In that case, some techniques widely depend on system voltage, and other techniques depending on system power (active or reactive), current, and frequency. Overall, signals and systems are related to each other in several aspects. That is to say, if you want to completely know about the behaviour of the electrical system then it is necessary to explore the signal processing techniques. This makes you monitor, control, and safeguard the systems.

What is a Signal?

A physical phenomenon that continuously changes over a specific period is known as a signal. Here, communication information transmits in the form of electrical signals through a communication channel/medium. As well, the signal is considered as a function with one or more variables that are not dependent on one another. Noisy information is a signal but it is not useful to consider a signal. For instance: wired signal, audio signal, video signal, etc.

What is a System?

A device or integrated device that is used to process electrical signals to generate the processed signal as the outcome is known as a system. Here, system input is referred to as excitation and corresponding system output is referred to as response. When the system is handling one or more inputs, it also produces one or more output. For instance: Communication System
