The first Razer Naga was announced at Gamescom 2009 [1] and released in August 2009. [2] The first version of the Naga had a total of seventeen buttons, [3] with twelve being on the left side of the mouse, and a switch on the underside of the mouse that maps them to the keyboard's top number buttons or its numeric keypad.

The Razer DeathAdder gaming mouse introduced in 2006 is the company's most popular mouse line by sales, [47] having sold over 20 million units worldwide by June 2024. [48] Razer mice are used by around 8% of professional first-person shooter gamers. [49] In 2021, Razer introduced a new 8 kHz "HyperPolling" technology to power the Razer Viper 8K ...
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.
Light sensitivity or photosensitivity refers to a notable or increased reactivity to light. Apart from vision , human beings have many physiological and psychological responses to light. In rare individuals an atypical response may result in serious discomfort, disease, or injury.
Spectral sensitivity is the relative efficiency of detection, of light or other signal, as a function of the frequency or wavelength of the signal. In visual neuroscience , spectral sensitivity is used to describe the different characteristics of the photopigments in the rod cells and cone cells in the retina of the eye .
People with protanopia have essentially no sensitivity to light of wavelengths more than 670 nm. Most non-primate mammals have the same luminous efficiency function as people with protanopia. Their insensitivity to long-wavelength red light makes it possible to use such illumination while studying the nocturnal life of animals. [18]
Measurement from a spectrum analyzer showing a noise-like measurement from an unspecified component.. In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system, where noise is defined as any signal other than the one being monitored.
