    1 microsecond – the length of time of a high-speed, commercial strobe light flash (see air-gap flash). 1 microsecond – protein folding takes place on the order of microseconds (thus this is the speed of carbon-based life). 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake.

    The rapid-fire computer-based HFT developed gradually since 1983 after NASDAQ introduced a purely electronic form of trading. [21] At the turn of the 21st century, HFT trades had an execution time of several seconds, whereas by 2010 this had decreased to milli- and even microseconds. [22]

    0.001 s A millisecond (from milli- and second ; symbol: ms ) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000 ) of a second [ 1 ] [ 2 ] or 1000 microseconds .

  8. Bandwidth (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Bandwidth_(signal_processing)

    The magnitude response of a band-pass filter illustrating the concept of −3 dB bandwidth at a gain of approximately 0.707 In some contexts, the signal bandwidth in hertz refers to the frequency range in which the signal's spectral density (in W/Hz or V 2 /Hz) is nonzero or above a small threshold value.

  9. Picosecond - Wikipedia

    This corresponds to a wavelength of 0.3 mm, as can be calculated by multiplying 1 ps by the speed of light (approximately 3 x 10 8 m/s) to determine the distance traveled. 1 THz is in the far infrared. 1 picosecond – time taken by light in vacuum to travel approximately 0.30 mm; 1 picosecond – half-life of a bottom quark
