Acoustic specialists have developed a computer model which allows them to calculate noise levels along the entire Swiss rail network. The program describes how much sound is radiated and how it is ...

Real-world signals, such as vibration, temperature, pressure, and light, require accurate signal conditioning and signal conversion before further data processing in the digital domain. In order to ...

The op amp's process technology and design techniques affect its noise performance. Analog IC designers use internal circuit tricks to reduce the bias current of bipolar transistors using bias current ...

This article describes the composite current source (CCS) noise modelfor cell-level noise analysis. CCSisa modeling capability in the open-source Liberty cell modeling standardthat encompasses timing, ...

Input-referred calculations are a valuable tool to understand the expected performance of a measurement system, helping to optimize designs and inform system specifications. Why input-referred ...

Transportation noise, largely from road, railway and aircraft traffic, is one of the most widespread sources of environmental stress and discomfort in daily life. Health effects of noise may emerge ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

WASHINGTON, January 18, 2022 -- Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise ...

A first-of-its-kind computer can perform calculations using the random “noise” that is inherent in our world. It is built using standard commercial components and could eventually run artificial ...

In a bid to reduce the impact of aircraft noise on local communities, Stockholm Bromma airport is on the verge of erecting a transparent perimeter wall that will minimise the sound of its operations, ...

Goods trains move at night because during daytime the Swiss rail system is used to full capacity by passenger traffic. Unfortunately, it is goods trains which make the most noise – and they operate at ...
