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?
a) both stations begin to transmit at the same time b) one station begins to transmit at the first possible moment such that its transmission would not be detected by the other station before it began its transmission
Write a program to find the sum of the elements of an array called list1. The size of list1 is four bytes. The values of list1 are $FF, $1, $FE, and $02. To check your work, the sum should become $0200.
