A 2W power signal is transmitted through a 40Km cable. A at a distance from the source of 24 km, an amplifier / repeater is placed with a gain of 64dB. The cable has an attenuation constant of 2.5dB/km. Determine a power of the signal at the input of the repeater and at the output of the communications system, that is, at the destination.
