  2. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    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.

  3. Slew rate - Wikipedia

    en.wikipedia.org/wiki/Slew_rate

    For example, when the input to a digital circuit is driven too slowly, the digital input value registered by the circuit may oscillate between 0 and 1 during the signal transition. [1] In other cases, a maximum slew rate is specified [ 2 ] in order to limit the high frequency content present in the signal, thereby preventing such undesirable ...

  4. Time-activity curve - Wikipedia

    en.wikipedia.org/wiki/Time-activity_curve

    The concept is explained with an example below. Consider a dynamic image where each table represents an image, obtained at different times, let's say at time t=1 sec, t=2 sec, t=3 sec, t=4 sec, t=5 sec, and t=6 sec. In this image, let's assume, each voxel shows the concentration of tracer in the units Bq per ml.

    1.44 minutes, or 86.4 seconds. Also marketed as a ".beat" by the Swatch corporation. moment: 1/40 solar hour (90 s on average) Medieval unit of time used by astronomers to compute astronomical movements, length varies with the season.

    1 ns: The time needed to execute one machine cycle by a 1 GHz microprocessor 1 ns: The time light takes to travel 30 cm (11.811 in) 10 −6: microsecond: μs One millionth of one second 1 μs: The time needed to execute one machine cycle by an Intel 80186 microprocessor 2.2 μs: The lifetime of a muon

  7. Time constant - Wikipedia

    en.wikipedia.org/wiki/Time_constant

    First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.

    1 millisecond (1 ms) – cycle time for frequency 1 kHz; duration of light for typical photo flash strobe; [5] time taken for sound wave to travel about 34 cm; repetition interval of GPS C/A PN code; 1 millisecond – time taken for light to travel 204.19 km in a single mode fiber optic cable for a wavelength of 1550 nm (frequency: 193 THz).
