2. Free-space path loss - Wikipedia

   en.wikipedia.org/wiki/Free-space_path_loss

   In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air). [1]

3. Path loss - Wikipedia

   en.wikipedia.org/wiki/Path_loss

   Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. [1] Path loss is a major component in the analysis and design of the link budget of a telecommunication system. This term is commonly used in wireless communications and signal propagation.

4. Attenuator (electronics) - Wikipedia

   en.wikipedia.org/wiki/Attenuator_(electronics)

   100 Watt power attenuator. An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than ...

5. Rain fade - Wikipedia

   en.wikipedia.org/wiki/Rain_fade

   It is possible to extrapolate the cumulative attenuation distribution at a given location by using the CCIR interpolation formula: [12] A p = A 001 0.12 p −(0.546 − 0.0043 log 10 p). where A p is the attenuation in dB exceeded for a p percentage of the time and A 001 is the attenuation exceeded for 0.01% of the time.

6. Line filter - Wikipedia

   en.wikipedia.org/wiki/Line_filter

   The attenuation of line filters is measured in two areas: Common mode - attenuation to signals that appear identically on each of the wires going through the filter. [1] Differential mode - attenuation to signals that appear on just one of the lines. [1] For each Mode, the attenuation is characterized over the frequency spectrum, and measured ...

7. Attenuation - Wikipedia

   en.wikipedia.org/wiki/Attenuation

   The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:

   From the figure the received line of sight component may be written as = {() /}and the ground reflected component may be written as = {() (+ ′) / + ′}where () is the transmitted signal, is the length of the direct line-of-sight (LOS) ray, + ′ is the length of the ground-reflected ray, is the combined antenna gain along the LOS path, is the combined antenna gain along the ground-reflected ...
