Digital-noise reduction with decoupling capacitors in ever faster (lower voltage/impedance) technologies for mixed-signal applications is being gradually rendered ineffective by line resistance to the capacitors.
In contrast, blocking inductors show excellent noise reduction in SPICE simulations, the LdI/dt self-perturbance being solved with local auxiliary capacitors.
Our experiment may become a powerful facility to test quantum noise reduction schemes such as the use of squeezed light or quantum locking of mirrors.
A mechanism of current noise reduction in systems of ion beam formation from vacuum arc plasma
Noise reduction by diaphragming laser beam in the optical detection system of an atomic force microscope
In this paper, a new method for nonlinear filtering of images based on trace transform is suggested; it can be used to reduce noise, quantize images, and construct their polygonal approximations.
Making clear the generation mechanism of fluid dynamic noise is essential to reduce noise deriving from turbomachinery.
This paper presents a new edge detector using 5×5 mask, which can reduce noise efficiently but not increase the width of the detected edge which always happens in the case of using the 5×5 window edge detector.
By means of optimization technique, the optimum operational parameters for two working conditions of the engine were selected and the test results showed that optimum adjustment could reduce noise by 2-4 dB.
This study investigates how to reduce noise and vibration in aircraft cabins with Pb(TiZr)O3 (PZT), using a semi-monocoque structure 1.5 m in diameter and 3.0 m long with a 2.3 mm skin, which simulates an aircraft body.
It is a first step towards a full simulation of a helicopter rotor equipped with a noise reducing passive control device in hover and in forward flight conditions.
The proposed switching rule is easily realizable, the noise reducing method is effective, and the whole recursive optimization algorithm is simply calculated.
Estimate of the noise reducing capability of a radar system from the directional characteristics of the antenna
We propose an estimate of the noise reducing capability of a radar system taking into account the side lobe structure of the directional characteristics of the antenna and the sensitivity of the receiver.
A test board was constructed and placed in a noise reducing faraday cage.
