A 50 km communication line has the following parameters: series resistance (R) = 21.4 W/km series inductance (L) = 1.0 mH/km shunt capacitance (C) = 0.062 mF/km shunt conductance (G) = 0.868 mS/km The frequency is 796 Hz and the line is terminated to avoid reflection. If the power at the receiving end is to be –20 dB (6mW reference) and the sending end voltage is 362 V, determine the power at the sending end.
