Outline Of Radio
The following outline is provided as an overview of and topical guide to radio:
Radio – transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, phase, or pulse width. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.

Famous quotes containing the words outline of, outline and/or radio:
“It is the business of thought to define things, to find the boundaries; thought, indeed, is a ceaseless process of definition. It is the business of Art to give things shape. Anyone who takes no delight in the firm outline of an object, or in its essential character, has no artistic sense.... He cannot even be nourished by Art. Like Ephraim, he feeds upon the East wind, which has no boundaries.”
—Vance Palmer (1885–1959)

“Denouement to denouement, he took a personal pride in the
certain, certain way he lived his own, private life,
but nevertheless, they shut off his gas; nevertheless,
the bank foreclosed; nevertheless, the landlord called;
nevertheless, the radio broke,
And twelve o’clock arrived just once too often,”
—Kenneth Fearing (1902–1961)
