Signals- a well-acquainted term, isn't it? It's a polyvalent word; it holds different meanings under different domains. Basically, it is any physical quantity that carries some information that can be called a signal. The physical quantities like temperature, pressure, humidity, etc. are continuously monitored in a process. Usually, the information carried by a signal is a function of some independent variable. In electrical engineering, the essential quantity of depicting some information is called a signal. It does not matter what the information is i-e: Analog or digital information. A system is interpreted by the kind of input and output it deals with. Since we are negotiating with signals, so in our instance, our system would be a mathematical model, a piece of code/software, or a physical device, or a black box.
