Radio receiverIn radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna responds to radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information.
Signal transmissionIn telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. EtymologyThe origin of the words transmit and transmission and their derivatives go back to the Latin word transmittere, in turn formed by prefixing the preposition trans (“across or beyond”) and the verb mittere (“to let go or to send”).

Radio broadcastingRadio broadcasting is the transmission of signals, especially audio, to receivers using radio waves over a wide area. Listeners require a broadcast radio receiver to receive these signals. "Terrestrial" broadcasts come from stations on land, and include AM and FM (both analog); and DAB (digital). Audio is also broadcast via satellite in both digital and analog, originating from a satellite in orbit around Earth.LaserDiscOptical analog video disc format LaserDiscA LaserDisc being heldMedia typeOptical discEncodingNTSC, PAL, MUSE, HD‑MAC, PALplusCapacity60/64 minutes on CLV30/36 minutes on CAV(NTSC/PAL, per side)Read mechanism780 nm laser diode (early players used He–Ne laser)StandardLaserVisionDeveloped byMCAPhilipsPioneerDimensionsCommon: 300 mm (11.8 in)Less common: 200 mm (7.9 in), 120 mm (4.7 in)UsageHome videoExtended toCDDVDLV-ROMReleasedDecember 11, 1978 (1978-12-11) (as DiscoVision)1980 (as LaserDisc)DiscontinuedSeptember 21, 2001 (films)July 2009 (production) LaserDisc (LD) is a home video format and the first commercial optical disc storage medium.
