Signals are nothing more than functions defined with respect to some independent variable, which we take to be time for the most part. ![]() Exactly what we mean by the "structure of a signal" will unfold in this section of the course. By definition, elemental signals have a simple structure. 2.2: Elemental Signals Elemental signals are the building blocks with which we build complicated signals.Fluency with complex numbers and rational functions of complex variables is a critical skill all engineers master. Representing sinusoids in terms of complex exponentials is not a mathematical oddity. 2.1: Complex Numbers While the fundamental signal used in electrical engineering is the sinusoid, it can be expressed mathematically in terms of an even more fundamental signal: the complex exponential.
