    L-shaped traffic pattern indicators are part of the segmented circle, a visual indicator system designed to provide traffic pattern information. [1] In aviation, a traffic pattern indicator is an L-shaped device which show the airfield traffic pattern to the in-flight aircraft over an aerodrome. [2] The short arm of the "L" represents the base ...

    The most common suspensions are 4–3 suspension, 7–6 suspension, or 9–8 suspension. Note that except for the 9–8 suspensions, the numbers are typically referred to using the simple intervals , so for instance, if the intervals are actually an 11th and a 10th (the first example below), one would typically call it a 4–3 suspension .

    Below the complex spherical harmonics are represented on 2D plots with the azimuthal angle, , on the horizontal axis and the polar angle, , on the vertical axis.The saturation of the color at any point represents the magnitude of the spherical harmonic and the hue represents the phase.

    In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized.

  8. Pythagorean tuning - Wikipedia

    en.wikipedia.org/wiki/Pythagorean_tuning

    Extended Pythagorean tuning corresponds 1-on-1 with western music notation and there is no limit to the number of fifths. In 12-tone Pythagorean temperament however one is limited by 12-tones per octave and one cannot play most music according to the Pythagorean system corresponding to the enharmonic notation.

  9. Window function - Wikipedia

    en.wikipedia.org/wiki/Window_function

    Planck–Bessel window, ε = 0.1, α = 4.45 A § Planck-taper window multiplied by a Kaiser window which is defined in terms of a modified Bessel function . This hybrid window function was introduced to decrease the peak side-lobe level of the Planck-taper window while still exploiting its good asymptotic decay. [ 75 ]
