Synchronization of Chaotic Maps by Symmetric Common Noise
, 1998 Synchronization of identical chaotic systems subjected to common noise has been the subject of recent research. Studies on several chaotic systems have shown that, the synchronization is actually induced by the non-zero mean of the noise, and symmetric ...

Low NF Active Quasi‐Circulator Design Based on Noise Suppression Technique
IET Microwaves, Antennas & PropagationIn this paper, an active quasi‐circulator (QC) exhibiting a low noise figure (NF) of 1.1 dB is presented, which is composed of two couplers, three connecting transmission lines (TLs) and a nonreciprocal stage.

Noise figure measurement concept for acoustic amplifiers [PDF]
, 1968 Optimum length buffer crystals are used with an amplification section for measuring the noise figure for acoustic amplifiers. Measuring the time required to saturate with noise a signal, which is reflected back and forth in the circuit, gives a direct ...

Pareto Optimal Characterization of a Microwave Transistor
IEEE Access, 2020 Herein, noise, gain and port mismatchings of a microwave small-signal transistor are expressed as all the set of acceptable Pareto optimal solutions and trade-off relations within the device operation (VDS, IDS,f) domain without any need of expert ...

Experimental characterization of photon-number noise in Rarity-Tapster type interferometers
, 2017 In this paper, we develop a simple model describing inherent photon-number noise in Rarity-Tapster type interferometers. This noise is caused by generating photon pairs in the process of spontaneous parametric down-conversion and adding a third photon by
