Lecture 2: Signals and systems: part I - MIT OpenCourseWare
ocw.mit.eduSinusoidal signals for both continuous time and discrete time will be-come important building blocks for more general signals, and the representa-tion using sinusoidal signals will lead to a very powerful set of ideas for repre-senting signals and for analyzing an important class of systems. We consider a

gvpcew.ac.inExponential and Sinusoidal Signals: Exponential and sinusoidal signals are characteristic of real-world signals and also from a basis (a building block) for other signals. A generic complex exponential signal is of the form: where C and a are, in general, complex numbers. Lets investigate some special cases of this signal
SINUSOIDAL SIGNALS - Åbo Akademi
users.abo.fiWHY SINUSOIDAL SIGNALS? † Physical reasons: - harmonic oscillators generate sinusoids, e.g., vibrating structures - waves consist of sinusoidals, e.g., acoustic waves or electromagnetic waves used in wireless transmission † Psychophysical reason: - speech consists of superposition of sinusoids - human ear detects frequencies
