Extracted text: 4) Assume a receiver is located 10 km from a 50 W transmitter. The carrier frequency is 900 MHz, free space propagation is assumed, G 1, and G, = 2, find %3D a) the power at the receiver, b) the magnitude of the E-field at the receiver antenna, c) the rms voltage applied to the receiver input assuming that the receiver antenna has a purely real impedance of 50 N and is matched to the receiver. [Ans: -61.52 dBm; 3.87mV/m; 0.374mV]
