7. A certain cable signal transmission system is shown. The nominal level at the signal source output is 10 dBm. The signal is amplified before transmission by the line amplifier whose gain is 13 dB. The first section of cable (section A) has a loss of 26 dB, and a booster amplifier with a gain of 20 dB is placed at the output of that section. The second section of cable (section B) has a loss of 29 dB. The system is operated on a matched impedance basis with all effective sources and termination having a resistive impedance of 600 N, and the characteristic impedance of the cable is the same. Determine the gain of the receiver amplifier such that its nominal output level is 6 V across a 600-N termination. 20 dB 26 dB 29 dB 10 dBm 13 dB - ???
