What is the maximum frequency (in GHz) that a single-line bus with a length of 1 meter can operate at without experiencing significant signal degradation, assuming a rise/fall time of 10% of the signal period and a characteristic impedance of 50 ohms?
In line-of-sight radio system, losses are mainly due to free space path loss (FSPL). FSPL is proportional to the square of the distance between the transmitter and receiver as well as the square of the frequency of the radio signal. Observe the FSPL for the situation below. a) For fixed frequency at 2600 MHz, calculate and sketch the graph of FSPL at the range of 1 km, 10 km, and 30 km. b) For fixed frequency at 5.8 GHz, calculate and sketch the graph of FSPL at the range of 1 m, 10 m, 100 m and 1 km.
Given the Digital Cellular System 1800 (DCS1800) with the transmitted power of 50 W from a base station (BS).

The BS is located 10 km away from the MS and the height of the antenna for the BS and MS are 150 m and 5 m, respectively. By assuming the two-ray ground reflection model between the BS and MS, calculate: (a) The received signal level at the MS. (b) The received signal path loss at the MS in dB.

The break point is at 10dB up to which the path loss is given by [ ] , beyond that point the path loss exponent is 3.8, and the fading margin is 10dB. What is the minimum Tx power required?

.Antennas and Propagation The audio power of the human voice is concentrated at about 300 Hz.
