  2. Cutoff frequency - Wikipedia

    en.wikipedia.org/wiki/Cutoff_frequency

    The cutoff frequency of an electromagnetic waveguide is the lowest frequency for which a mode will propagate in it. In fiber optics, it is more common to consider the cutoff wavelength, the maximum wavelength that will propagate in an optical fiber or waveguide.

  3. Cutoff (physics) - Wikipedia

    en.wikipedia.org/wiki/Cutoff_(physics)

    In theoretical physics, cutoff (AE: cutoff, BE: cut-off) is an arbitrary maximal or minimal value of energy, momentum, or length, used in order that objects with larger or smaller values than these physical quantities are ignored in some calculation.

  4. Cutoff - Wikipedia

    en.wikipedia.org/wiki/Cutoff

    Cutoff frequency, in telecommunications and digital signal processing. Cutoff grade, in mining, the level of mineral in an ore below which it is not economically feasible to mine it. Cutoff voltage, the voltage at which a battery is considered fully discharged. Fuse (electrical) (or cutoff), a type of overcurrent protection device.

  5. Cut-off low - Wikipedia

    en.wikipedia.org/wiki/Cut-off_low

    A cut-off low (or cutoff low), sometimes referred to as the weatherman's woe, is defined by the National Weather Service as "a closed upper-level low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current."

  6. Cut-off (electronics) - Wikipedia

    en.wikipedia.org/wiki/Cut-off_(electronics)

    In electronics, cut-off is a state of negligible conduction that is a property of several types of electronic components when a control parameter (that usually is a well-defined voltage or electric current, but could also be an incident light intensity or a magnetic field), is lowered or increased past a value (the conduction threshold).

  7. Spatial cutoff frequency - Wikipedia

    en.wikipedia.org/wiki/Spatial_cutoff_frequency

    In optics, spatial cutoff frequency is a precise way to quantify the smallest object resolvable by an optical system. Due to diffraction at the image plane, all optical systems act as low pass filters with a finite ability to resolve detail.

  8. Cutoff (steam engine) - Wikipedia

    en.wikipedia.org/wiki/Cutoff_(steam_engine)

    In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear.. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine.

  9. Cutoff voltage - Wikipedia

    en.wikipedia.org/wiki/Cutoff_voltage

    The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...
