Noise figures (linear transducers) [PDF]
IEEE Transactions on Education, 1989 A short tutorial description of noise figures for two-port linear transducers and entire receiver systems is presented. Due to the long history and of the use of noise figures to specify noise performance, numerous definitions have evolved. The relationship between the various noise-figure definitions found in the literature are specified and tables ...

Dynamics of a FitzHugh-Nagumo system subjected to autocorrelated noise [PDF]
, 2008 We analyze the dynamics of the FitzHugh-Nagumo (FHN) model in the presence of colored noise and a periodic signal. Two cases are considered: (i) the dynamics of the membrane potential is affected by the noise, (ii) the slow dynamics of the recovery ...

Performance of DPSK Signals with Quadratic Phase Noise
, 2004 Nonlinear phase noise induced by the interaction of fiber Kerr effect and amplifier noises is a quadratic function of the electric field. When the dependence between the additive Gaussian noise and the quadratic phase noise is taking into account, the ...

Displacement-noise-free gravitational-wave detection with a single Fabry-Perot cavity: a toy model
, 2008 We propose a detuned Fabry-Perot cavity, pumped through both the mirrors, as \textit{a toy model} of the gravitational-wave (GW) detector partially free from displacement noise of the test masses.

Neural entrainment to pitch changes of auditory targets in noise
NeuroImageNeural entrainment to certain acoustic features can predict speech-in-noise perception, but these features are difficult to separate. We measured neural responses to both natural speech-in-noise and stimuli (auditory figure-ground) that simulate speech ...

Nonmonotonic Pattern Formation in Three Species Lotka-Volterra System with Colored Noise [PDF]
, 2005 A coupled map lattice of generalized Lotka-Volterra equations in the presence of colored multiplicative noise is used to analyze the spatiotemporal evolution of three interacting species: one predator and two preys symmetrically competing each other. The
