2. Attenuator (electronics) - Wikipedia

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

   An RF microwave attenuator. Key specifications for attenuators are: [2] Attenuation expressed in decibels of relative power. A 3 dB pad reduces power to one half, 6 dB to one fourth, 10 dB to one tenth, 20 dB to one hundredth, 30 dB to one thousandth and so on.

3. 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:

4. 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).

   Cooking spray and an air fryer are the perfect pairing, but it's important to remember that, unlike when cooking in a skillet, it's the food that should be sprayed, not the air fryer basket.

6. RF and microwave filter - Wikipedia

   en.wikipedia.org/wiki/RF_and_microwave_filter

   Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). It is component that is used in electronic systems to pass or reject specific frequencies and attenuate of unwanted signals within the ...

7. Radio over fiber - Wikipedia

   en.wikipedia.org/wiki/Radio_over_fiber

   Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical ...

8. ITU model for indoor attenuation - Wikipedia

   en.wikipedia.org/wiki/ITU_Model_for_Indoor...

   The ITU indoor propagation model, also known as ITU model for indoor attenuation, is a radio propagation model that estimates the path loss inside a room or a closed area inside a building delimited by walls of any form. Suitable for appliances designed for indoor use, this model approximates the total path loss an indoor link may experience.

9. Radio frequency - Wikipedia

   en.wikipedia.org/wiki/Radio_frequency

   Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.
