Problem 7: The one-way bandwidth available to a single operator in the AMPS system is 12.5 MHz with a channel bandwidth of 30 kHz and 21 control channels. We would like to calculate the efficiency with which this system utilizes bandwidth for a particular installation. Use the following parameters: - Cell area = 8 km^2 - Total coverage area = 4000 km^2 - Frequency reuse factor = 9 - Average number of calls per user during busy hour = 1.5 calls/user - Average holding time of a call = 120 s/call - Call blocking probability = 1% a. How many voice channels are there per cell? (0.3p) b. Use Table 13.1 and a simple straight-line interpolation to determine the total traffic carried per cell, in Erlangs/cell. Then convert that to Erlangs/km^2. (0.3p) c. Calculate the number of calls/hour/cell and the number of calls/hour/km^2. (0.2p) d.

l Duty does not need to be based on any particular end, but rather itself occasions a new end for the human will, that of striving with all one's power towards the highest good possible on earth. 2. Corrected_text: The humanist revolution caused modern Western culture to lose faith and interest in superior mental states and to sanctify the mundane experience of the average Joe. 3. Corrected_text: Modern Western culture is therefore unique in lacking a specialized class of people who seek to experience extraordinary mental states. 4. Corrected_text: Dawkins has called pantheism a sexed-up atheism. 5. Corrected_text: Man's dissatisfaction with the order of nature is the shortness of life.

Water flows from a tank of constant cross-sectional area 60 ft² through an orifice of constant cross-sectional area 1.4 ft² located at the bottom of the tank. Initially, the height of the water in the tank was 20 ft, and t sec later is given by the equation $2\sqrt{h} + \frac{1}{30}t - 2\sqrt{20} = 0$, $0 \le t \le 60\sqrt{20}$. Differentiate the given equation with respect to t. $\frac{dh}{dt} = \text{________}$ How fast (in ft/s) was the height of the water decreasing when its height was 4 ft? ________ ft/s
