mixing

  1. The result of irregular fluctuations in fluid motions on all scales from the molecular to large eddies.

    Gradients of conservative properties such as potential temperature, momentum, humidity, and concentrations of particles and gaseous constituents are reduced by mixing, tending toward a state of uniform distribution.
    See turbulence, eddy flux, diffusion.

  2. In electronics, the nonlinear (nonadditive) combining of signals.

    The common mixing element is a diode or set of diodes. The common desired result of mixing two sinusoidal signals is the multiplicative product, with terms at the sum and difference frequencies. Mixing is used to shift signals to different carrier frequencies.
