Direct Measuring the Amplitude Ratios of Weakly Coupled Resonators Employing Automatic Amplitude Control

IEEE Transactions on Instrumentation and Measurement, 2021
Since the eigenstate-modulated weakly coupled resonators (WCRs) characterize the detected signals by measuring the amplitude ratios of weakly coupled resonant units, the convenient and accurate extraction of amplitude ratios becomes critical for high-performance applications of all mode-localized sensors.

A Maximal Afterpulse Amplitude-to-Main Pulse Amplitude Ratio in a Photomultiplier Tube

Instruments and Experimental Techniques, 2002
An amplitude dependence of afterpulses caused by an ion feedback on the main pulse amplitudes in a photomultiplier tube is studied. It has been found that a maximal afterpulse amplitude-to-maximal main pulse amplitude ratio is inversely proportional to the main pulse amplitude.

Degradation of signal-to-noise ratio due to amplitude distortion

IEEE Transactions on Information Theory, 1989
The effect of filtering on the signal-to-noise ratio (SNR) of a coherently demodulated band-limited signal is determined in the presence of worst-case amplitude ripple. The problem is formulated as an optimization in the Hilbert space L/sub 2/. The form of the worst-case amplitude ripple is specified, and the degradation in the SNR is derived in closed

New Monte Carlo Estimates of critical interfacial amplitudes and the universality of amplitude ratios

Physical Review Letters, 1988
Les amplitudes de la tension interfaciale critique sont obtenues sans calculer l'exces d'energie libre. Des calculs Monte Carlo avec de tres larges dimensions de reseau sont faits. Un modele d'Ising cubique simple est traite. Les desaccords entre les experiences et la theorie sur l'universalite des rapports d'amplitudes sont ...

BAEP amplitudes and amplitude ratios: relation to click polarity, rate, age and sex

Electroencephalography and Clinical Neurophysiology, 1991
BAEP amplitudes and amplitude ratios in 47 healthy subjects aged 4-58 years have been investigated with respect to the simultaneous influence of stimulus polarity, rate, sex and age. The sex effect (larger amplitudes in women than in men) seemed to be most pronounced for wave IV-V amplitude, while the age effects (decreasing amplitudes with age) seem ...

Universality in surface growth: Scaling functions and amplitude ratios

Physical Review A, 1992
A scaling analysis of a variety of nonlinear equations for surface growth is presented. It predicts the existence of universal scaling functions and amplitude ratios for the surface width w(L,t) on length scale L at time t and for the height-difference correlation function G(x,t).

Universal critical amplitude ratios for percolation

Physical Review B, 1980
The hypothesis of universality implies that for every scaling relation among critical exponents there exists a universal ratio among the corresponding critical amplitudes. If one writes $B{|t|}^{\ensuremath{\beta}}$, ${{A}_{F}}^{\ifmmode\pm\else\textpm\fi{}}{|t|}^{2\ensuremath{-}\ensuremath{\alpha}}$, ${C}^{\ifmmode\pm\else\textpm\fi{}}{|t ...

Amplitude ratios near a Lifshitz point

Canadian Journal of Physics, 2001
The susceptibility amplitude ratio in the neighborhood of an m-fold Lifshitz point is calculated using the field theoretical techniques of the renormalization group, in one-loop order. A simple expression for the amplitude associated with the helical (ferromagnetic) AH (AF) branches near a Lifshitz point is also calculated.
