Specific Attenuation Solution

STEP 0: Pre-Calculation Summary
Formula Used
Specific Attenuation = Total Attenuation/Effective Path Length
α = A/Leff
This formula uses 3 Variables
Variables Used
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.
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.
STEP 1: Convert Input(s) to Base Unit
Total Attenuation: 360 Decibel --> 360 Decibel No Conversion Required
Effective Path Length: 12 Kilometer --> 12000 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
α = A/Leff --> 360/12000
Evaluating ... ...
α = 0.03
STEP 3: Convert Result to Output's Unit
0.03 Decibel --> No Conversion Required
FINAL ANSWER
0.03 Decibel <-- Specific Attenuation
(Calculation completed in 00.020 seconds)
