Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Popular Songs (Yo La Tengo album)

Popular Songs is the twelfth full-length album by Hoboken-based rock band Yo La Tengo, released digitally, on CD, and double LP on September 8, 2009. It is their 7th album released on Matador and the eighth album to be given Matador's Buy Early Get Now treatment, in which it came along with a vinyl LP featuring Yo La Tengo’s Original Score from the film, Adventureland, as well as three bonus tracks as download in MP3 and FLAC. The first two of these downloads were demo versions of two album tracks and became available shortly before the release of the CD. The third download became available on December 15, 2009. The same track is also available in the iTunes Store and on the Japanese CD issue of the album.

Four videos were made by director John McSwain to accompany one song from the album each. In the weeks leading up to the release of the album, a new video was posted on Matador's various "partner sites" and collected on Matador's own website. The first video, for "Here to Fall," was posted on Matador's own "Matablog" on July 28, 2009.
