Specific Attenuation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Attenuation = Total Attenuation/Effective Path Length
α = A/L_eff
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/L_eff --> 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
