Consider the communication system shown in Fig. 9-37 (P9.22), with all components properly matched. If Pt = 10 W and f =6 GHz:
(a) What is the power density at the receiving antenna (assuming proper alignment of antennas)?
(b) What is the received power?
(c) If Tsys = 1000 K and the receiver bandwidth is 20 MHz, what is the signal to noise ratio in dB?
