Noise (electronics)

random signal having equal intensity at different frequencies, giving it a constant power spectral density

measure comparing the level of a searched signal to the level of background noise

process of mapping a continuous set to a countable set

type of signal whose amplitude is inversely proportional to its frequency

random fluctuation in an electrical signal

Thermal noise present in all electrical circuits

power spectrum of a noise signal (a signal produced by a stochastic process)

The kind of signal noise produced by Brownian motion

pseudo-random signal with characteristics similar to noise

Signal-to-noise and distortion ratio (SNDR) is a term used for a set of measures of the quality of a signal from a communications device. These include SINAD and SINADR.

random noise whose frequency spectrum follows a psychoacoustic equal loudness curve
