The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible, and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.
All electronic musical instruments can be viewed as a subset of audio signal processing applications. Simple electronic musical instruments are sometimes called sound effects; the border between sound effects and actual musical instruments is often hazy.
Electronic musical instruments are now widely used in most styles of music. Development of new electronic musical instruments, controllers, and synthesizers continues to be a highly active and interdisciplinary field of research. Specialized conferences, notably the International Conference on New Interfaces for Musical Expression, have organized to report cutting-edge work, as well as to provide a showcase for artists who perform or create music with new electronic music instruments, controllers, and synthesizers.
Electronics was an Americantrade journal that covered the radio industry and its later spin-offs in the mid-to-late 20th century. Its first issue was dated in April 1930. The periodical was published under the title Electronics until 1984, when it changed temporarily to the new title ElectronicsWeek, but then reverted again to the original title Electronics in 1985. The ISSN for the corresponding periods are: 0013-5070 for the 1930–1984 issues, 0748-3252 for the 1984–1985 issues with title ElectronicsWeek, and 0883-4989 for the 1985–1995 issues. It was published by McGraw-Hill until 1988, when it was sold to the Dutch company VNU. VNU sold its American electronics magazines to Penton Publishing the next year.
Generally a monthly magazine, its frequency and page count varied with the state of the industry, until its end in 1995. More than its principal rival Electronic News, it balanced its appeal to managerial and technical interests (at the time of its 1992 makeover, it described itself as a magazine for managers). The magazine was best known for publishing the April 19, 1965 article by Intel co-founder Gordon Moore, in which he outlined what came to be known as Moore's Law.
The PowerBook G3 is a line of laptop Macintosh computers produced by Apple Computer between 1997 and 2001. It was the first laptop to use the PowerPC G3 (PPC740/750) series of microprocessors. It was succeeded by the Titanium PowerBook G4 line in 2001, which used the PowerPC G4 (PPC74xx) series of microprocessors.
PowerBook G3 (Kanga)
The first Macintosh PowerBook G3, code-named "Kanga," was introduced in November 1997. At the time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available (a title formerly held by its predecessor, the 240MHz PPC-603ev-based PowerBook 3400c). This model was based on the PowerBook 3400c, and was unofficially known as the PowerBook 3500. It used the same case as the 3400c, and a very similar motherboard. The motherboard was upclocked from 40MHz to 50MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to the motherboard included doubling the on-board RAM from 16 MB to 32 MB, and a faster version of the on-board Chips and Technologies graphics controller. The G3 made the Kanga more than twice as fast as a 3400c, and the improved graphics controller allowed it to refresh the screen 74 percent faster.
