Detection of amplitude modulation with squeezed light for sensitivity beyond the shot-noise limit [PDF]
, 1988 An improvement in precision beyond the limit set by the vacuum-state or zero-point fluctuations of the electromagnetic field is reported for the detection of amplitude modulation encoded on a weak signal beam. The improvement is achieved by employing the

The Influence of the Signal-to-Noise Ratio upon Radio Occultation Retrievals
Remote Sensing, 2022 We study the dependence of radio occultation (RO) inversion statistics on the signal-to-noise ratio (SNR). We use observations from four missions: COSMIC, COSMIC-2, METOP-B, and Spire.

Force feedback linearization for higher-order electromechanical sigma-delta modulators.
, 2005 A higher-order electromechanical sigma–delta modulator can greatly improve the signal-to-noise ratio compared with a second-order loop that only uses the sensing element as a loop filter.

Non-uniformity of Clinical Head, Head and Neck, and Body Coils in Magnetic Resonance Imaging (MRI) [PDF]
Iranian Journal of Medical Physics, 2014 Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio ...

Optical signal to noise ratio improvement through unbalanced noise beating in phase-sensitive parametric amplifiers [PDF]
, 2014 We investigate the beating of signal and idler waves, which have imbalanced signal to noise ratios, in a phase-sensitive parametric amplifier. Imbalanced signal to noise ratios are achieved in two ways; first by imbalanced noise loading; second by ...
