Abstract: In this letter, we study the impact of quadrature imbalance (QI) on the performance of optical communications systems using polarization-division-multiplexed (PDM) quadrature phase-shift ...

Abstract: A fully-integrated quadrature low-IF L1-band GPS receiver consumes only 6.4 mW in 0.13 μm CMOS. The RF front-end features a gate-modulated quadrature VCO for low phase noise and accurate ...

Optical loss degrades quantum correlations, hindering the use of quantum quadrature entanglement for many applications. Researchers have now experimentally demonstrated that this entanglement can be ...

This video tutorial demonstrates how to use and leverage 3 key new features found under the Effects tab in Adobe Media Encoder CC (which replaces the much more limited Filters tab in Adobe Media ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

As a very nice touchy-feely user interface, Anders has sourced a range of chunky rotary knob quadrature encoders that have a circular colour display in the middle – hundreds of pixels across. The ...

Digital quadrature encoders have become a standard for precision automation systems used in laser materials processing, additive manufacturing (AM), and test/inspection. In these tools, stage-level ...
