## threshold

1. Psychol the strength at which a stimulus is just perceived
2.
a. the minimum intensity or value of a signal, etc., that will produce a response or specified effect
b. (as modifier): a threshold current

## Threshold

A strip fastened to the floor beneath a door, to cover the joint where two types of floor materials meet or to provide weather protection.

## What does it mean when you dream about a threshold?

A threshold is a symbol for passing from one state or condition to the next, indicating a transition in some aspect of the dreamer’s life.

## threshold

[′thresh‚hōld]
(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.

## threshold

The beginning of that portion of the runway usable for landing (ICAO). On instrument runways, it is indicated by long stripes followed by the runway designation marking. The number of stripes is dependent on the width of the runway.

## threshold

(1) The point at which a signal (voltage, current, etc.) is perceived as valid.
