The neper (symbol: Np) is a logarithmic unit for ratios of measurements of physical field and power quantities, such as gain and loss of electronic signals. The unit's name is derived from the name of John Napier , the inventor of logarithms.
α is called the neper frequency, or attenuation, and is a measure of how fast the transient response of the circuit will die away after the stimulus has been removed. Neper occurs in the name because the units can also be considered to be nepers per second, neper being a logarithmic unit of attenuation. ω 0 is the angular resonance frequency. [3]
Neper is an old lunar impact crater located near the eastern limb of the Moon. Due to its location the crater must be viewed during a suitable libration , and is very foreshortened. The crater lies on the south edge of Mare Marginis , to the east of the crater Jansky .
A resistor–capacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors.It may be driven by a voltage or current source and these will produce different responses.
John Napier of Merchiston (/ ˈ n eɪ p i ər / NAY-pee-ər; [1] Latinized as Ioannes Neper; 1 February 1550 – 4 April 1617), nicknamed Marvellous Merchiston, was a Scottish landowner known as a mathematician, physicist, and astronomer. He was the 8th Laird of Merchiston. John Napier is best known as the discoverer of logarithms.
A field level (or root-power level) is a logarithmic quantity used to measure quantities of which the square is typically proportional to power (for instance, the square of voltage is proportional to power by the inverse of the conductor's resistance), etc., with commonly used units neper (Np) or decibel (dB).
Naturally, as lord of the mouth, Neper's mother was identified as Renenutet, who gave out the ren, a person's true name, and who was also identified as a source of nourishment. In particular, Neper was especially associated with the most used types of grain, namely barley and emmer wheat. His name simply means "lord of the mouth", a reference ...
Neper is a logarithmic unit of ratio. Neper may also refer to: John Napier, a Scottish mathematician; Neper (crater), a lunar impact crater; Neper (mythology), an ...
