Abstract: An analytical model linking the demodulated phase precision and system parameters for standard heterodyne-detection phase-sensitive optical time-domain reflectometry ( $\Phi$-OTDR) is ...

Encouraged by these findings, they then set out to test their hypothesis in an experimental setting, using real quantum circuits. "In our experiment, we observed the signature of the phase ...

The Natural Hazards Detection System (NHDS) Program is a $3.3 million multi-phased competitive challenge grant aimed at testing innovative detection technologies with eligible companies who offer ...

but the design of the building block is all digital circuit. B. Architecture There are some major building blocks in the proposed ADPLL. They are phase/frequency detector (PDF), gain generation unit, ...

The present IP is a VCC Detector (VDT) circuit, which prevents the possibilities of causing ... The output may be in the wrong voltage level during the power-up phase before the bandgap becomes stable ...
