Question

A signal of power 6 mW is transmitted through a cable. If the signal encounters a loss of 6db due to impairments of the transmission medium. Calculate the power received at the receiver end.

Answer 1

3 db is half, so 6 db is half of half.
power out=6mW(1/4)=1.5mWatts

Powerout=6mw*10^-.6=1.5mW
