A sound amplification technique from SLS Loudspeakers (Springfield, MO) promises to reduce the size and cost of high-power, professional quality speakers. The approach, dubbed Evenstar, uses a pair of ...
The transition from second-generation (2G) to third-generation (3G) wireless cellular systems requires multi-standard adaptability in a wireless receiver. An important answer to this request is the ...
Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...
Researchers devised an electro-optical modulator that can be fabricated using standard CMOS processes and achieve over 100-Gb/s performance, with power requirements of 2 pJ/bit. Due to materials ...
This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design, ...
OpenLight and Tower Semiconductor have announced a successful demonstration of a 400G/lane modulator on Tower's silicon photonics platform, PH18DA, which achieves over a 3.5dB extinction ratio using ...
