Question
A signal passes through a 10-meter cable, an amplifier, and then a filter. The amplifier has an output that is eight times higher in power than its input. Each meter of cable reduces the signal level by a factor of 4. The filter has a loss of 5 dB. What is the total loss/gain of the three elements in series?
