A transmission line is loaded by a 96 % efficiency antenna that radiates 35 Watts into space. The antenna has a 30 dB gain and has a radiation resistance of 85-ohm. This line is loaded by a matched source TX. The receiver antenna is located 5 Km from the transmitter antenna and the frequency is 900 MHz.
1. What is the total power absorbed by the transmitting antenna?
2. What is the total resistance of the antenna?
3. What is the Loss in Free Space in ratio value and in dB?
4. What is the received power induced in the receiver antenna?
5. What is the effective area of the receiver antenna?
6. What is the electric field around the receiver antenna?
The message signal x(t), in the following system has a nabdwidth of 10kHz. The center frequecy of the Narrow Band Frequency Modulated (NBFM) signal nbfm(f) is 1Mhz, the frequency deviation f1=1khz and the amplitude of the NBFM signal is 1V.
Determine which of these properties hold or don't hold for the following discrete time systems. Justify your answers. IN each example, y(t) denotes the system output and x(t) denotes the system input.
