3. To get some idea on what is involved in digital transmission of multimedia traffic, complete the following:

3.1. In PAM encoding, the general rule is that we need to sample at twice the bandwidth. In addition, if we use n bits for each sample, we can represent 2n loudness (amplitude) levels. What transmission speed would you need if you wanted to encode and transmit, in real time and without compression, two-channel music with a bandwidth of 20 kHz and 40,000 loudness levels?

3.2. How much disk space would your require to store 30 minutes of digital music as you calculated above?

3.3. Assume that the 30 minutes of uncompressed digital music is to be transmitted over a DS-0 digital circuit at 64 Kbps. How long will it take to complete the transmission? Express you result in hours/minutes if necessary.

A key idea in this book is that “You get what you measure!” Essentially, this means that performance measures have a great influence on the behavior of managers. Select a company with which you are familiar. Identify three performance measures that the company might use. For each measure, identify a favorable outcome and an unfavorable outcome that might occur because the measure is used to evaluate manager performance.

Sampling Distributions: To get an idea of what is going on when you are talking about a sampling distribution, consider a population of 5 test scores from a small class. The test scores are {100, 95, 90, 85, 80}. Let us obtain samples of size 2 from this population with replacement. In other words, after you select the first test score, you put it back for selection again. Sampling with replacement from a small population is similar to sampling from...
