power spectral density method
11Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… …

13Code division multiple access — This article is about a channel access method. For the mobile phone technology referred to as CDMA, see IS 95 and CDMA2000. Multiplex techniques Circuit mode (constant bandwidth) TDM · FDM  …
14Shannon–Hartley theorem — In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. It is an application of the noisy channel coding… …
15Periodogram — The periodogram is an estimate of the spectral density of a signal. The term was coined by Arthur Schuster in 1898Schuster, A., On the investigation of hidden periodicities with application to a supposed 26 day period of meteorological phenomena …
16Bluetooth — This article is about the electronic protocol. For the medieval King of Denmark, see Harald I of Denmark. Bluetooth logo Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength …
17Detrended fluctuation analysis — In stochastic processes, chaos theory and time series analysis, detrended fluctuation analysis (DFA) is a method for determining the statistical self affinity of a signal. It is useful for analysing time series that appear to be long memory… …

19Wiener deconvolution — In mathematics, Wiener deconvolution is an application of the Wiener filter to the noise problems inherent in deconvolution. It works in the frequency domain, attempting to minimize the impact of deconvoluted noise at frequencies which have a… …
20Decibel — This article is about the ratio of measures. For sound or acoustic level, see Sound pressure. For other uses, see Decibel (disambiguation). Attenuation chart of an RG 6 Coaxial cable, measured in decibels per 100 feet of cable The decibel (dB) is …
