  2. Orthogonality principle - Wikipedia

    en.wikipedia.org/wiki/Orthogonality_principle

    Conversely, if the noise variance is relatively higher, then the estimate will be close to m, as the measurements are not reliable enough to outweigh the prior information. Finally, note that because the variables x and y are jointly Gaussian, the minimum MSE estimator is linear. [ 2 ]

  3. Noise curve - Wikipedia

    en.wikipedia.org/wiki/Noise_curve

    Noise curves are a common way to characterise background noise in unoccupied buildings and spaces. [1] Their purpose is to produce a single-value representation of a complete sound spectrum. International standards organizations ( ISO , [ 2 ] ANSI [ 3 ] and ASA ) recognize the need to objectify judgements on the amount of ambient noise in ...

  4. MUSIC (algorithm) - Wikipedia

    en.wikipedia.org/wiki/MUSIC_(algorithm)

    Schmidt, in particular, accomplished this by first deriving a complete geometric solution in the absence of noise, then cleverly extending the geometric concepts to obtain a reasonable approximate solution in the presence of noise. The resulting algorithm was called MUSIC (MUltiple SIgnal Classification) and has been widely studied.

  5. Signal averaging - Wikipedia

    en.wikipedia.org/wiki/Signal_averaging

    Signal averaging is a signal processing technique applied in the time domain, intended to increase the strength of a signal relative to noise that is obscuring it. By averaging a set of replicate measurements, the signal-to-noise ratio (SNR) will be increased, ideally in proportion to the square root of the number of measurements.

  6. Noise regulation - Wikipedia

    en.wikipedia.org/wiki/Noise_regulation

    A typical noise ordinance sets forth clear definitions of acoustic nomenclature and defines categories of noise generation; then numerical standards are established, so that enforcement personnel can take the necessary steps of warnings, fines or other municipal police power to rectify unacceptable noise generation.
