Question

You have deployed your Ethernet cable near a generator, whose heat is effecting the cable in a way that its energy is lost. If signal has a power of 2 mW before passing near the generator and it becomes 1.4 mW after passing near the generator. How much is the attenuation?

Answer 1

1.55 dB

Step-by-step explanation:

Attenuation to 1.4/2.0 = 0.7 of the previous power level is a gain of ...

10·log(0.7) = -1.549 dB

The signal is attenuated by 1.55 dB.
