A geostationary satellite is at a distance of 40,000 km m a ground receiving station. The satellite transmitting enna is a circular aperture with a 1-m diameter, and the round station uses a parabolic dish antenna with an effective meter of 20 cm. If the satellite transmits 1 kW of power at GHz and the ground receiver is characterized by a system se temperature of 1,000 K, what would be the signal-to-noise io of a received TV signal with a bandwidth of 6 MHz? The ennas and the atmosphere may be assumed lossless.
