Sinusoidal Steady-state Analysis
In electrical engineering, sinusoidal forcing functions are particularly important. The alternating sinusoidal current of power frequencies (50 Hz, 60 Hz) is extensively used for producing, transmitting and utilizing electric energy in industry and in the home. High-frequency sinusoids (of kilohertz, megahertz and gigahertz) are used as carrier signals for communication purposes. Sinusoids are in abundance in nature, as, for example, in the movement of a pendulum, in the bouncing of a ball, and in the vibrations of strings and membranes.
