Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...

Noise is the real enemy of data communications. Whenever electrons travel over a wire or radiate through space, they generate some electromagnetic noise. Therefore, whenever a data signal is sent ...

This study comes from Prof. Duanduan Wan and Prof. Meng Xiao group at the School of Physics of Wuhan University. This work provides a simple while intuitive example by demonstrating with both theory ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...
