Advocacy group La Quadrature du Net rallies opposition to ACTA As controversial anti-piracy legislation stalls in the US, a European group of free internet supporters, La Quadrature du Net, calls for a halt to similar legislation in the European Union.
Simple clear advice in plain English The French advocacy group La Quadrature du Net today accused the European Commission of "plainly lying" to the European Parliament about the Anti-Counterfeiting Trade Agreement (ACTA).
ETRI tests DP-QPSK alternative for 100-Gbps metro networks Korea’s Electronics and Telecommunications Research Institute (ETRI) says it has successfully trialed a 100-Gbps optical transceiver that uses an alternative to coherent-enabled dual-polarization quadrature phase-shift keying ( DP-QPSK ). The patent-pending modulation format, called dual-carrier differential quadrature phase-shift keying (DC-DQPSK) requires neither a DSP ASIC nor polarization ...
GigOptix samples 100G coherent optical modulator GigOptix, Inc. (OTCQX:GGOX), a supplier of high-speed electronic and electro-optic components, says it has begun sampling the LX8240, a 100G dual-polarization quadrature phase-shift keying ( DP-QPSK ) Mach-Zehnder modulator (MZM).
Analog Devices’ D/A Converter Reduces Cable Head-end Signal Chain Footprint Analog Devices, Inc. , the data converter market share leader*, today introduced an 11-bit D/A converter that enables cable television and broadband operators to synthesize the entire cable spectrum up to 1 GHz into a single RF port, while consuming a maximum of 1.1 W of power.
High-Performance AFE suits femtocells, portable SDR applications. Supplied in 9 x 9 mm QFN package, 12-bit AFE7225 integrates dual 125 MSPS ADC and dual 250 MSPS DAC. For power-sensitive applications, 12-bit AFE7222 integrates dual 65 MSPS ADC and dual 130 MSPS DAC and uses 398 mW in full-duplex or 212 mW in half-duplex receive mode at full speed. Both mixed-signal analog front ends (AFEs) integrate DSP with independent transmit and receive, 32-bit NCOs ...
Protests erupt across Europe against web piracy treaty BERLIN/SOFIA (Reuters) - Tens of thousands of protesters took part in rallies across Europe on Saturday against an international anti-piracy agreement they fear will curb their freedom to download movies and music for free and encourage Internet surveillance. More than 25,000 demonstrators braved freezing temperatures in German cities to march against the Anti-Counterfeiting Trade Agreement ...
