The gradual loss of color of a paint film due to a chemical or physical change Usually due to pigment degradation by the ultraviolet (UV) radiation in sunlight
Variation in the field strength or other properties of a received radio wave signal as a result of changes in the electromagnetic field propagation characteristic of the transmission path with time
Fading describes rapid changes in a radio signals amplitude over a short period of time or travel distance Fading is a result of multipath In fact, it is caused by interference between multiple replicas of the transmitted signal
The reduction in signal intensity of one or several of the components of a radio signal, typically caused by the reflective or refractive effects of multi-path
