  2. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:

  3. Attenuation coefficient - Wikipedia

    en.wikipedia.org/wiki/Attenuation_coefficient

    The attenuation coefficient of a volume, denoted μ, is defined as [6] =, where Φ e is the radiant flux;; z is the path length of the beam.; Note that for an attenuation coefficient which does not vary with z, this equation is solved along a line from =0 to as:

  4. Propagation constant - Wikipedia

    en.wikipedia.org/wiki/Propagation_constant

    Attenuation constant can be defined by the amplitude ratio | A 0 A x | = e α x {\displaystyle \left|{\frac {A_{0}}{A_{x}}}\right|=e^{\alpha x}} The propagation constant per unit length is defined as the natural logarithm of the ratio of the sending end current or voltage to the receiving end current or voltage, divided by the distance x involved:

  5. Attenuation-to-crosstalk ratio - Wikipedia

    en.wikipedia.org/wiki/Attenuation-to-crosstalk_ratio

    Attenuation-to-crosstalk ratio (ACR) is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. [1] AcR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs. [ 2 ]

  6. Acoustic wave equation - Wikipedia

    en.wikipedia.org/wiki/Acoustic_wave_equation

    In physics, the acoustic wave equation is a second-order partial differential equation that governs the propagation of acoustic waves through a material medium resp. a standing wavefield. The equation describes the evolution of acoustic pressure p or particle velocity u as a function of position x and time t. A simplified (scalar) form of the ...

  7. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    α is called the neper frequency, or attenuation, and is a measure of how fast the transient response of the circuit will die away after the stimulus has been removed. Neper occurs in the name because the units can also be considered to be nepers per second, neper being a logarithmic unit of attenuation. ω 0 is the angular resonance frequency. [3]

  9. Stokes's law of sound attenuation - Wikipedia

    en.wikipedia.org/wiki/Stokes's_law_of_sound...

    In acoustics, Stokes's law of sound attenuation is a formula for the attenuation of sound in a Newtonian fluid, such as water or air, due to the fluid's viscosity.It states that the amplitude of a plane wave decreases exponentially with distance traveled, at a rate α given by = where η is the dynamic viscosity coefficient of the fluid, ω is the sound's angular frequency, ρ is the fluid ...
