A satellite in geosynchronous orbit is used as a regenerative repeater in a digital communication system. Consider the satellite-to-earth link in which the satellite antenna has a gain of 6 dB and the earth station antenna has a gain of 50 dB. The downlink is operated at a center frequency of 4 GHz, and the signal bandwidth is 1 MHz. If the required εb/N₀ for reliable communication is 15 dB, determine the transmitted power for the satellite downlink. Assume that N₀ = 4.1 × 10^-21 W/Hz.
