bandlimit (plural bandlimits)

1. (physics) The limiting frequency of a signal beyond which the intensity of the signal is zero
   • 2015, Achim Kempf, Angus Prain, “Driving Quantum Systems with Superoscillations”, in arXiv‎:

     We conclude that, either superoscillations really can beat the bandlimit and achieve superresolution (`kinematic superresolution') or the superoscillating high frequency is absorbed and we gain dynamical access to the physics of high frequency processes with low frequency signals (`dynamical superresolution')..
