plural of shot noise

plural of Poisson noise

The power of the noise in a signal.

A signal or process with a frequency spectrum such that the spectral energy density is proportional to the reciprocal of the frequency (1/f).

(physics) A random signal (or process) with a flat power spectral density; a signal with a power spectral density that has equal power in any band, at any centre frequency, having a given bandwidth.

Excess noise which is unpleasant or harmful.

(electrical engineering) The ratio comparing signal power to noise power. / (by extension) The quantity of quality information compared to irrelevant or incorrect information.

(computing) Spurious characters due to signal noise in a communications link. / (programming) Data that looks random, as when outputting a binary file as text.

(finance) One who trades financial products (such as stocks) not based on fundamental analysis.

(computer graphics) Random-looking visual noise generated by a function, widely used in computer graphics to simulate effects such as fire and clouds.
