Total Attenuation Solution

Follow our step by step solution on how to calculate Total Attenuation?

FIRST Step Consider the formula

A = L eff \cdot α

Next Step Substitute values of Variables

∴

A = 12km \cdot 0.03dB

Next Step Convert Units

∴

A = 12000m \cdot 0.03dB

Next Step Prepare to Evaluate

∴

A = 12000 \cdot 0.03

LAST Step Evaluate

∴

A = 360dB

Total Attenuation Formula Elements

Variables

Total Attenuation

Total Attenuation refers to the reduction in signal strength or intensity as a signal travels through a medium, often due to factors like absorption, scattering, and diffraction.

Symbol: A

Measurement: SoundUnit: dB

Note: Value can be positive or negative.

Formulas to find Total Attenuation

Effective Path Length

Effective Path Length refers to the total distance that a radio signal travels between a transmitter and a receiver, taking into account the effects of multipath propagation.

Symbol: L_eff

Measurement: LengthUnit: km

Note: Value should be greater than 0.

Formulas to find Effective Path Length

Specific Attenuation

Specific attenuation refers to the loss of signal power due to various atmospheric phenomena that affect the transmission of electromagnetic waves between a satellite and an Earth station.

Symbol: α

Measurement: SoundUnit: dB

Note: Value can be positive or negative.

Go Earth Station Altitude

h o = h rain - L slant \cdot \sin (∠θ el)

Go Effective Path Length using Reduction Factor

L eff = L slant \cdot r p

Go Rain Height

h rain = L slant \cdot \sin (∠θ el) + h o

How to Evaluate Total Attenuation?

Total Attenuation evaluator uses Total Attenuation = Effective Path Length*Specific Attenuation to evaluate the Total Attenuation, Total Attenuation refers to the combined effect of various factors that cause a reduction in the intensity or strength of a signal as it propagates through a medium or along a transmission path. These factors can include absorption, scattering, reflection, diffraction, and other interactions with the medium. Total attenuation accounts for all the losses and reductions in signal strength along the entire transmission path. Total Attenuation is denoted by A symbol.
