Consumer electronics & Digital Products

Consumer electronics include electronic equipment intended for everyday use. Consumer electronics are most often used in entertainment, communications and office productivity. Some products classed as consumer electronics include personal computers, telephones, MP3 players, audio equipment, televisions, calculators, GPS automotive navigation systems, digital cameras and playback and recording of video media such as DVDs, VHSs or camcorders. Currently, the global consumer electronics industry is mainly dominated by Japanese and South Korean companies.

The CEA (Consumer Electronics Association) estimates 2007 US Consumer Electronics sales at 150 billion dollars.

Consumer electronics are manufactured throughout the world, although there is a particularly high concentration of research and development activity in Japan and South Korea. The latest consumer electronics are previewed yearly at the Consumer Electronics Show in Las Vegas, Nevada, at which many industry pioneers speak.

Digital electronics are systems that represent signals as discrete levels, rather than as a continuous range. In most cases the number of states is two, and these states are represented by two voltage levels: one near to zero volts and one at a higher level depending on the supply voltage in use. These two levels are often represented as “Low” and “High.”

The fundamental advantage of digital techniques stem from the fact it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.

Digital electronics are usually made from large assemblies of logic gates, simple electronic representations of Boolean logic functions.
