Active Control of Broadband Noise Inside a Car Using a Causal Optimal Controller [PDF]

open access: goldApplied Sciences, 2019
This paper investigates active broadband noise control inside vehicles with a multichannel controller. The noncausal inversion of a practical nonminimum-phase secondary path is formulated, and its influence on noise-reduction performance is analyzed ...

Improved Separation of Tone and Broadband Noise Components from Open Rotor Acoustic Data

open access: yesAerospace, 2016
The term “open rotor” refers to unducted counter-rotating dual rotors or propellers used for propulsion. The noise generated by an open rotor is very complicated and requires special techniques for its analysis.

Characterizing Broadband Seismic Noise in Central London [PDF]

open access: yesSeismological Research Letters, 2016
ABSTRACT Recordings made at five broadband seismometers, deployed in central London during the summer of 2015, reveal the wideband nature (periods T of between 0.01 and 100 s) of anthropogenic noise in a busy urban environment. Temporal variations of power spectral density (PSD) measurements suggest that transportation sources generate the majority ...

The Accretion Flow Geometry of MAXI J1820+070 through Broadband Noise Research with Insight Hard X-ray Modulation Telescope [PDF]

open access: yesAstrophysical Journal, 2022
Here we present a detailed study of the broadband noise in the power density spectra of the black hole X-ray binary MAXI J1820+070 during the hard state of its 2018 outburst, using Hard X-ray Modulation Telescope observations.

Mathematical model of spatial and temporal processing of broadband signals in satellite radio systems of broadband access and radio navigation

open access: yesКосмические аппараты и технологии, 2023
To effectively receive a useful broadband signal, it is necessary to compensate for distortions caused by the complex frequency-dependent coefficient of the receiving and transmitting antenna, multiplicative interference and noise from the heterogeneity ...

Variable-Temperature Noise Characterization of N-MOSFETs Using an In-Situ Broadband Amplifier

open access: yesIEEE Journal of the Electron Devices Society, 2021
Characterization of broadband noise of MOSFETs from room temperature down to 120 K in fine temperature steps is presented. A MOSFET is mounted on a reusable printed circuit board vehicle with a built-in low-noise amplifier, and the vehicle is loaded into

Investigation of the Noise Induced by Unstable Flow in a Centrifugal Pump

open access: yesEnergies, 2020
In order to investigate the mechanism and the characteristics of the noise induced by unstable flow in a centrifugal pump, the internal flow characteristics in the pump were numerically researched, and the acoustic pressure fluctuations at the pump inlet
