Low-Frequency noise investigation of AlGaN/GaN high-electron-mobility transistors
(2021-09-01)
In this paper, the noise Power Spectral Density (PSD) of AlGaN/GaN High-Electron-Mobility Transistors (HEMTs) has been experimentally investigated in linear operation (VD = 50 mV) for different channel lengths (L) and ...
High-frequency Audiometry Hearing On Monitoring Of Individuals Exposed To Occupational Noise: A Systematic Review
(Fundação Otorrinolaringologia, 2016)
The effect of noise variation over time and between populations on the fine spectrotemporal characteristics of different vocalization types
(2021-01)
Noise affects the recognition of acoustic signals by masking information. To compensate for increased noise, individuals often increase the minimum frequency of their vocalization to reduce noise interference. Our goal was ...
OFDM tolerance to additive white Gaussian and laser phase noises in optical heterodyning systems accompanied by the feasible pilot-assisted equalization
(Optical Society of Japan, 2020)
It is well known that the performance of orthogonal frequency division multiplexing (OFDM) is limited by phase noise, which depends on the laser linewidths for coherent-detection radio over fiber (RoF) systems. In this ...
An effective wavelet method to detect and mitigate low-frequency multipath effects
(2008-12-01)
To ensure high accuracy results from GPS relative positioning, the multipath effects have to be mitigated. Although the careful selection of antenna site and the use of especial antennas and receivers can minimize multipath, ...

Price discovery and market microstructure noise
(2019-01-21)
Using a continuous-time price discovery model, we show that the standard econometric framework typically yields inconsistent estimates of the price discovery measures in the presence of market microstructure noise due the ...
House Wrens Troglodytes aedon reduce repertoire size and change song element frequencies in response to anthropogenic noise
(2020-06-09)
Anthropogenic noise (≤ 3 kHz) can affect key features of birds’ acoustic communication via two different processes: (1) song-learning, because songbirds need to hear themselves and other birds to crystallize their song, ...
