fade time

Noun

fade time (countable and uncountable, plural fade times)

1. (film, television) The amount of time for a scene to fade to dark after lighting up.
2. (signal processing) The time during which a wireless signal is too faint to be accurately received.
   • 2006, Roger L. Freeman, Radio System Design for Telecommunications, page 31:

     The annual fade time is three times that occurring in a heavy fading month when the climate is average.

   • 2014, Arun K. Majumdar, Advanced Free Space Optics (FSO): A Systems Approach:

     The fractional fade time (also called the probability of fade) describes the percentage of time the irradiance of the received wave is below some given threshold value.

   • 2016, Murat Uysal, Carlo Capsoni, Zabih Ghassemlooy, Optical Wireless Communications: An Emerging Technology, page 95:

     The mean fade time decreases with increasing elevation and fade threshold.

   • 2021, Douglas H Morais, 5G and Beyond Wireless Transport Technologies, page 62:

     Figure 4.12 of [8] shows that on the same path from which the data in Fig. 4.11 of [8] was derived, for fade depth deeper than about 20 dB, the fade time decreases by a factor of about 10 for a 10 dB increase in fade depth.

3. (light engineering, sound engineering) The amount of time for light or sound from a specified source to fade in from nothingness to the maximum that one is using, or to fade out from the maximum to nothingness.
   • 2015, Michelle M. Fernandez, Corona SDK Mobile Game Development, page 183:

     Omitting this parameter invokes a default fade time, which is 1,000 milliseconds.

   • 2019, J. Michael Gillette, Michael McNamara, Designing with Light: An Introduction to Stage Lighting:

     The time is used to assign a fade time to a cue.

   • 2021, Brad Schiller, The Automated Lighting Programmer's Handbook:

     If the fade time is set to ten seconds, then they will fade up their intensity over a ten second crossfade. Changing the fade time of the cue will adjust the fade time for all parameters stored within that cue.
