  2. SWR meter - Wikipedia

    en.wikipedia.org/wiki/SWR_meter

    A standing wave ratio meter, SWR meter, ISWR meter (current "I" SWR), or VSWR meter (voltage SWR) measures the standing wave ratio (SWR) in a transmission line. [ a ] The meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna ).

  3. Formula One engines - Wikipedia

    en.wikipedia.org/wiki/Formula_One_engines

    As energy loss increases nearly exponentially with engine speed, the rev limit became meaningless, so it was lifted in 2022. Currently, F1 engines rev up to about 13,000rpm, while the combustion efficiency has risen to about 40 bar BMEP and beyond, using lean and rapid burn techniques enabling λ<1 (average air/fuel ratio much leaner than 14.7 ...

  4. Reflections of signals on conducting lines - Wikipedia

    en.wikipedia.org/wiki/Reflections_of_signals_on...

    A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...

  5. Free-space path loss - Wikipedia

    en.wikipedia.org/wiki/Free-space_path_loss

    In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

  6. Slew rate - Wikipedia

    en.wikipedia.org/wiki/Slew_rate

    In mechanics the slew rate is the change in position over time of an object which orbits around the observer, measured in radians, degrees or turns per unit of time. It has dimension T − 1 . {\displaystyle {\mathsf {T}}^{{-}1}.}

  7. Mitsubishi 6A1 engine - Wikipedia

    en.wikipedia.org/wiki/Mitsubishi_6A1_engine

    The Mitsubishi 6A1 engine is a series of piston V6 engines from Mitsubishi Motors, found in their small and medium vehicles through the 1990s.They ranged from 1.6 to 2.5 L (1,597 to 2,498 cc) in size, and came with a variety of induction methods and cylinder head designs and configurations.

  8. Rate of return - Wikipedia

    en.wikipedia.org/wiki/Rate_of_return

    An annual rate of return is a return over a period of one year, such as January 1 through December 31, or June 3, 2006, through June 2, 2007, whereas an annualized rate of return is a rate of return per year, measured over a period either longer or shorter than one year, such as a month, or two years, annualized for comparison with a one-year ...

  9. Dissipation factor - Wikipedia

    en.wikipedia.org/wiki/Dissipation_factor

    The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or
