13Ultraviolet–visible spectroscopy — Beckman DU640 UV/Vis spectrophotometer. Ultraviolet visible spectroscopy or ultraviolet visible spectrophotometry (UV Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet visible spectral region. This… …
14Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… …
