Distributed Measurement of Signal Power Evolution in a Phase Sensitive Parametric Amplifier

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Fatemeh Alishahi, Andrey Denisov

A method to measure the signal power evolution along phase-sensitive parametric amplifiers is proposed using Brillouin optical time-domain analysis. Different evolutions along the fiber are reported by varying input wave phases, including amplification and ...

Rank-order equalization

Mohammad Amin Shokrollahi, Harm Cronie, Klaas Lammert Hofstra

For digital data transmitted using a vector signaling encoding, a rank-order equalizer cancels various channel noise such as inter-symbol interference. Further, rank-order units may be cascaded to achieve improved equalization over successive sample vector ...

Optimization of electroacoustic resonators for semi-active room equalization in the low-frequency range

Hervé Lissek, Etienne Thierry Jean-Luc Rivet

At low frequencies, standing waves within the room cause large frequency-response variations in the listening environment, such as audio rooms or recording studios. This unwanted phenomenon has a significant impact on the sound quality of an audio system. ...
