Television noise reduction device [PDF]
, 1975 A noise reduction system that divides the color video signal into its luminance and chrominance components is reported. The luminance component of a given frame is summed with the luminance component of at least one preceding frame which was stored on a ...

Reduction of Guided Acoustic Wave Brillouin Scattering in Photonic Crystal Fibers
, 2005 Guided Acoustic Wave Brillouin Scattering (GAWBS) generates phase and polarization noise of light propagating in glass fibers. This excess noise affects the performance of various experiments operating at the quantum noise limit.

Television noise-reduction device [PDF]
, 1973 System greatly improves signal-to-noise ratio with little or no loss in picture resolution. By storage of luminance component, which is summed with chrominance component, system performs mathematical integration of basically-repetitive television signals.

Noise Reduction Technique for Heart Rate Monitoring Devices [PDF]
, 2014 Electrocardiogram (ECG) signal has been widely used to detect the heart rate of the human, and it is useful in cardiac pathology. ECG detects several heart diseases of the patients.

Numerical investigation of a feed-forward linewidth reduction scheme using a mode-locked laser model of reduced complexity [PDF]
, 2018 We provide numerical verification of a feed-forward, heterodyne-based phase noise reduction scheme using single-sideband modulation that obviates the need for optical filtering at the output.

Optimal phase space projection for noise reduction [PDF]
, 2005 In this communication we will re-examine the widely studied technique of phase space projection. By imposing a time domain constraint (TDC) on the residual noise, we deduce a more general version of the optimal projector, which includes those appearing ...

Reduction of noise in gyro outputs [PDF]
, 1972 Technique is described to reduce extraneous gyro output signals by using relatively inexpensive shrouds which do not increase power comsumption. Shrouds reduce noise by minimizing mass of gas spinning with rotor, reducing Reynolds number near rotor, and ...

Elliptical side resonators for broadband noise reduction: theory and experiments [PDF]
, 2006 Previous research of the authors pointed out that side-resonators can be applied to reduce fan noise. However, the noise reduction capabilities of most resonator geometries, e.g.

Suppression of Shot Noise in Quantum Point Contacts in the "0.7" Regime [PDF]
, 2006 Experimental investigations of current shot noise in quantum point contacts show a reduction of the noise near the 0.7 anomaly. It is demonstrated that such a reduction naturally arises in a model proposed recently to explain the characteristics of the 0.

Amplitude-phase decorrelation: a method for reducing intensity noise in semiconductor lasers [PDF]
, 1991 It has been shown that the method of amplitude-phase decorrelation can reduce the fundamental intensity noise floor of semiconductor laser light over a wide bandwidth by the ratio 1/(1+α^2), where α is the linewidth enhancement factor.
