Signal definition EC6303 Signals and Systems Notes

A signal is a function representing a physical quantity or variable, and typically it contains information about the behaviour or nature of the phenomenon.
For instance, in a RC circuit the signal may represent the voltage across the capacitor or the current flowing in the resistor. Mathematically, a signal is represented as a function of an independent variable ‘t’. Usually ‘t’ represents time. Thus, a signal is denoted by x(t). 1.1.2

System definition EC6303 Signals and Systems Notes

A system is a mathematical model of a physical process that relates the input (or excitation) signal to the output (or response) signal. Let x and y be the input and output signals, respectively, of a system. Then the system is viewed as a transformation (or mapping) of x into y. This transformation is represented by the
mathematical notation
y= Tx —————————————–(1.1)
where T is the operator representing some well-defined rule by which x is transformed into y. Relationship (1.1) is depicted as shown in Fig. 1-1(a). Multiple input and/or output signals are possible as shown in Fig. 1-1(b). We will restrict our attention for the most part in this text to the single-input, single-output case.
