(building construction)
A piece of stone, wood, or metal that lies under an outside door.
(electronics)
In a modulation system, the smallest value of carrier-to-noise ratio at the input to the demodulator for all values above which a small percentage change in the input carrier-to-noise ratio produces a substantially equal or smaller percentage change in the output signal-to-noise ratio.
(engineering)
The least value of a current, voltage, or other quantity that produces the minimum detectable response in an instrument or system.
(geology)
(mathematics)
A logic operator such that, if P, Q, R, S, … are statements, then the threshold will be true if at least N statements are true, false otherwise.
(physics)
The minimum level of some input quantity needed for some process to take place, such as a threshold energy for a reaction, or the minimum level of pumping at which a laser can go into self-excited oscillation.
(physiology)
The minimum level of a stimulus that will evoke a response in an irritable tissue.

threshold

1. A strip fastened to the floor beneath a door, usually required to cover the joint where two types of floor material meet; may provide weather protection at exterior doors. Also See doorsill.
2. In illumination engineering, the value of physical stimulus which permits an object to be seen a specified percentage of the time with specified accuracy.
