Total Attenuation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Attenuation = Effective Path Length*Specific Attenuation
A = L_eff*α
This formula uses 3 Variables

Variables Used

Total Attenuation - (Measured in Decibel) - 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.
Effective Path Length - (Measured in Meter) - 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.
Specific Attenuation - (Measured in Decibel) - 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.

STEP 1: Convert Input(s) to Base Unit

Effective Path Length: 12 Kilometer --> 12000 Meter (Check conversion here)
Specific Attenuation: 0.03 Decibel --> 0.03 Decibel No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = L_eff*α --> 12000*0.03

Evaluating ... ...

A = 360

STEP 3: Convert Result to Output's Unit

360 Decibel --> No Conversion Required

FINAL ANSWER

360 Decibel <-- Total Attenuation

What is Attenuation?

Attenuation refers to the reduction in the intensity, power, or magnitude of a signal or wave as it travels through a medium. This reduction can occur due to various factors, including absorption, scattering, reflection, diffraction, and other interactions between the signal and the medium. Attenuation is a common phenomenon in various fields, including telecommunications, acoustics, optics, and electromagnetic propagation.

How to Calculate Total Attenuation?

Total Attenuation calculator uses Total Attenuation = Effective Path Length*Specific Attenuation to calculate 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.
