### Is the Nyquist theorem true for optical fiber or only for copper wire? How many end office codes were there pre-1984, when each end office was named by its three-digit area code and the first three digits of the local number? Area codes started with a digit in the range 2-9, had a 0 or 1 as the second digit, and ended with any digit. The first two digits of a local number were always in the range 2-9. The third digit could be any digit. What is the percent overhead on a T1 carrier; that is what percent of the 1.544 Mbps are not delivered to the end user? What is the difference between message switching network and packet switching? Sometimes when a mobile user crosses the boundary from one cell to another the current call is abruptly terminated even though all transmitters and receivers are functioning perfectly Why? A CDMA receiver gets the following chips: (+1 +1 +1 +1 +3 -1 -1 +3). Assuming the chip sequences for four stations as defined below, which stations transmitted, and which bit did each one send?

### Algorithm analysis for N elements

1) find the kth largest value in an unsorted array of N elements. Estimate the running time. It should be better than quick sort running time. I think O(n + klogn) is an efficient running time (if you can do a better algo, please do so). I don't need the entire program. Just functions that show the timing. This is how I did it.
