Under the Hood: Silicon TV tuners clearing hurdles Dec 26, 2007
Added to all these innovations is the imminent worldwide transition in TV broadcasting from to digital modulation. The digital TV revolution is developing rapidly; indeed, in some jurisdictions, analog broadcasts have already ceased. (EETimes)
Ultrawideband SoCs pose new challenges to manufacturers Oct 16, 2007
Answer: All use a complex digital modulation scheme to transfer data over the airwaves, all are a variant of orthogonal frequency division multiplexing (OFDM) and all will become standard capabilities in the next 18 to 24 months as consumer-driven demand for wireless applications hastens convergence of mobile audio, video and data. As advanced UWB wireless applications and ICs evolve, test technology must also evolve. (EETimes)
STMicroelectronics Creates 'Sound Terminal' Family of High-Quality, High-Efficiency, All-Digital Audio Solutions Jan 4, 2007
Already available as silicon prototypes, Sound Terminal products for portable applications include amplification enabled by ST's proprietary digital modulation technology (FFX), offering the highest amplifier efficiency in the market - up to 94% - to deliver 'cool audio power' and allow much longer battery life in portable systems, plus a significant reduction in heat-sink size to enable leading-edge product design. Embedded digital processing capability offers major opportunities for sound... (PR Newswire)
Nortel Flips the Channel to 4G Oct 13, 2006
MIMO can be used in conjunction with OFDM (orthogonal frequency-division multiplexing), the basis of a digital modulation scheme that is part of the IEEE 802. 16 standard and which will also be part of the IEEE 802. (eWeek)
Brazil Adopts Japanese Digital TV Standard on Costs, Consumer Efficiency Jun 30, 2006
Digital television sends signals via digital modulation data, which is digitally compressed. That uses less bandwidth, which frees up space for more channels. (Bloomberg -- Latin America)
