6. A 10-GHz line-of-sight microwave communication link consists of two lossless parabolic dish antennas, each has 40 dB gain. If the receiver antenna requires 3 nW of receive power for good reception and the distance between the antennas is 35 km, how much power (in both mW and dBm) should be transmitted?

In an experiment to demonstrate interference, you connect two antennas to a single radio receiver. When the two antennas are adjacent to each other, the received signal is strong. You leave one antenna in place and move the other one directly away from the radio transmission tower. Part A How far should the second antenna be moved in order to receive a minimum signal from a station that broadcasts at 92.9 MHz? Express your answer to three significant figures and...

9.) Two antennas, 6 meters (m) apart, transmit coherent, monochromatic radio waves, to two receivers, A and B. Receiver A is the same distance from both antennas (about 8.5 m). Receiver B is 8m from one antenna, and 10m from the other I both antennas transmit 3m waves with wavelength of 1.0 meters, then what type of interference will be experienced by the receivers? 8 A) receiver A: constructive; receiver B: constructive B.) receiver A: constructive; receiver...

1-An advantage of one-way communication over two-way is the fact that A-fewer mistakes or problems are likely to arise as work progresses. B-the receiver is more likely to understand what to do with the message. C-feedback allows for suggestions and modifications. D-communication is faster and easier. E-it is more accurate communication that ensures clarity. 2-A disadvantage of oral communication is that the A-sender has no control over where, when, or if the message is received. B-message is less persuasive than...
