A transmission line of length 
has an attenuation per unit length of 
. The input power to the transmission line is 
. The minimum acceptable signal-to-noise ratio is 
for background noise of 
.
Calculate the minimum acceptable power output from the transmission line.
Use your answer in (a) to determine whether it is possible to transmit the signal along the transmission line.
.
, which is greater than the minimum acceptable power output from the transmission line. So, it is possible to transmit the signal along the transmission line.
