Storage infrastructures form the backbone of data centers, as they hold the data owned by enterprises, government institutions, or private individuals. Various types of data centers exist to serve the purposes of different application areas, such as cloud storage, (industrial) internet of things or business models (such as software as a service or streaming portals), … Continue reading
Signal-to-noise ratio (SNR or S/N) is a measure used in many disciplines, but is most common in analyzing electrical signals. SNR is the ratio of the power of a signal (desired input) to the power of the background noise (undesired input). Typically, the signal power “is what it is” (that is, it can’t be controlled … Continue reading
When signal light is very precious, any background light that reaches the detector of an optical system can greatly compromise signal-to-noise ratio. If the signal is low, then the background must be maintained at an even lower level, and so background light must be minimized. For instance, in a Raman analytical system only one in … Continue reading
In designing a filter solution, the filter manufacturer takes the values requested by the user and adds additional design margin to account for both functional effects (such as wavelength shift due to angle variation, thermal induced wavelength shift, etc.) and filter manufacturing effects (such as edge steepness, non-uniformity, wavelength targeting – see Iridian’s technical note … Continue reading
