The fading of a received signal caused by different wave components traveling along slightly different paths.  2, record 1, English, - interference%20fading

Record number: 1, Textual support number: 1 CONT

Interference fading: As [the] name indicates, it is the fading produced because of upper and lower rays of the sky wave interfering with each other. This is the most serious fading. It is also produced due to the interference between a ground wave and a sky wave or between sky waves reaching [a] receiver by different paths or different number of hops. For a single sky wave frequency, interference fading takes place due to the fluctuations in the height of the ionospheric layer or due to the variation in the ionic density of the layer.  3, record 1, English, - interference%20fading

The ratio of maximum signal to minimum signal during fading, usually expressed in dB.  1, record 3, English, - fading%20range

Record number: 3, Textual support number: 1 CONT

Often the fading range is specified over a range of percentages. For example, the 5% to 95% fading range is the ratio of the signal exceeded 5% of the time to that exceeded 95% of the time.  1, record 3, English, - fading%20range

Frecuentemente, la gama de desvanecimiento se especifica a modo de escala de porcentajes. Por ejemplo, la gama de desvanecimiento 5% a 95% representa la relación entre la señal excedida el 5% del tiempo y la señal excedida el 95% del tiempo.  1, record 3, Spanish, - gama%20de%20desvanecimiento

In one arrangement, two identical radiofrequency systems, each with its own antenna, feed a common audio-frequency channel. In another arrangement, a single receiver is changed over from one antenna to the other by electronic switching at a rate fast enough to prevent loss of intelligibility.  1, record 4, English, - dual%20diversity%20reception

Reflections of a radio signal from different obstacles. The result is a series of reflected radio signals coming from different directions after travelling along different paths.
