Dead time

from Wikipedia, the free encyclopedia

dead time referred

  • the time span between a change at the system input and the corresponding response at the system output of a controlled system, see dead time (control technology) .
  • a period of time immediately after the detection of a particle during which a particle detector is not yet ready to detect another particle, see dead time (particle measurement technology) .
  • in the case of radar devices, the deliberately introduced time span between the end of the reception time and the next transmission pulse (see pulse repetition frequency )
  • In chromatography, the dead time is referred to as the retention time that the mobile phase needs to pass through the chromatographic system from injection to detection. It is not experimentally accessible. An experimentally accessible dead time, which is greater than the true dead time, is obtained by injecting and detecting a substance that does not take up any chromatographic interactions with the column, but does make its way through the pores of the stationary phase. (See also: Chromatography # flow time (dead time) )
  • In power electronics, the time span in which neither the upper nor the lower switch is closed in a bridge circuit . This prevents short-circuiting of the supply voltage. Occasionally, the literature also speaks of locking time.
