= Noise-equivalent power
{wiki=Noise-equivalent_power}
Noise-equivalent power (NEP) is a key parameter used to describe the sensitivity of a detector or sensor, often in the context of optical and infrared detectors. It quantifies the minimum power of an incoming signal that can be reliably detected above the noise level of the system. Specifically, NEP is defined as the incident power of a signal that produces a signal-to-noise ratio (SNR) of one when integrated over a given bandwidth.
