Attenuation Formula
Formula
A = 10 × log₁₀(P₀/P) dB
or
A = α × d
Where:
- • A = attenuation (dB)
- • P₀ = initial power (W)
- • P = final power (W)
- • α = attenuation coefficient (dB/m)
- • d = distance (m)
Typical Attenuation
- • Optical fiber: 0.2-0.5 dB/km
- • Coaxial cable: 0.1-1 dB/m
- • Air (radio): ~0.01 dB/km
- • Water (sound): ~0.1 dB/m
