## nanosecond

[′nan·ə‚sek·ənd]
(mechanics)
A unit of time equal to one-billionth of a second, or 10-9 second.

## nanosecond

(unit)
(ns) 10^-9 seconds; one thousand millionth part of a second.

This is the unit in which the fundamental logical operations of modern digital circuits are typically measured. For example, a microprocessor with a clock frequency of 100 megahertz will have a 10 nanosecond clock period.

## nanosecond

(1) One billionth of a second. Used to measure the speed of logic and memory chips, a nanosecond can be visualized by converting it to distance. In one nanosecond, electricity travels approximately a foot in a wire. Admiral Grace Hopper was famous for handing out strands of "telephone wire nanoseconds" to her audience whenever she lectured about technology. Holding the wire turns the unreal concept of a billionth of a second into reality.

Even at 186,000 miles per second, electricity is never fast enough for the hardware designer who worries over a few inches of circuit path. The slightest delay is multiplied millions of times, since billions of pulses are sent through a wire in a single second. In addition, today's chips contain more than a thousand feet of wire traces, which are the circuit pathways that carry electricity. See space/time, jiffy and ohnosecond.

(2) The time between a traffic light turning green and a New York City cab driver blowing his horn.

3 V signal with a 1 nsec rise time passes through a region where the quiet line runs co-parallel underneath the active line.
Sure enough, there is a negative dip after 1 nsec, a pretty large reflection.
If the speed of the signal is about 6 inches/nsec, then the condition of the stub time delay shorter than 20% of the rise time of the signal translates into this simple rule of thumb: The maximum stub length in inches, Len, should be kept shorter than the rise time in nsec, RT, or Len < RT.
