Specific Attenuation Solution

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

FIRST Step Consider the formula

α = \frac{A}{L eff}

Next Step Substitute values of Variables

∴

α = \frac{360dB}{12km}

Next Step Convert Units

∴

α = \frac{360dB}{12000m}

Next Step Prepare to Evaluate

∴

α = \frac{360}{12000}

LAST Step Evaluate

∴

α = 0.03dB

Specific Attenuation Formula Elements

Variables

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.

Formulas to find Specific Attenuation

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

Other formulas in Radio Wave Propagation category

Go Effective Path Length

L eff = \frac{A}{α}

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 Specific Attenuation?

Specific Attenuation evaluator uses Specific Attenuation = Total Attenuation/Effective Path Length to evaluate the Specific Attenuation, The Specific Attenuation formula is defined as is the fundamental quantity in the calculation of rain attenuation for terrestrial path and slant paths representing as rain attenuation per unit distance (dB/km). Specific Attenuation is denoted by α symbol.

How to evaluate Specific Attenuation using this online evaluator? To use this online evaluator for Specific Attenuation, enter Total Attenuation (A) & Effective Path Length (L_eff) and hit the calculate button.

FAQs on Specific Attenuation

What is the formula to find Specific Attenuation?

The formula of Specific Attenuation is expressed as Specific Attenuation = Total Attenuation/Effective Path Length. Here is an example- 0.001667 = 360/12000.

How to calculate Specific Attenuation?

With Total Attenuation (A) & Effective Path Length (L_eff) we can find Specific Attenuation using the formula - Specific Attenuation = Total Attenuation/Effective Path Length.

Can the Specific Attenuation be negative?

Yes, the Specific Attenuation, measured in Sound can be negative.

Which unit is used to measure Specific Attenuation?

Specific Attenuation is usually measured using the Decibel[dB] for Sound. Bel[dB], Neper[dB] are the few other units in which Specific Attenuation can be measured.
