Using the sound tools, figure out the characteristic pattern of different instruments. For example, pianos tend to have a pattern the opposite of what we created- the amplitudes decrease as we get to higher sine waves. Try creating a variety of patterns and see how they sound and how they look.
Note: This question simply requires an answer with a few examples of sounds and patterns.
Cramtrack, the regional commuter train system that runs between Southern New Jersey and New York City’s Penn Station, is trying to train users of its newly installed computer system. For the users to get the proper training, the systems analysts involved with the project sent a memo to the heads of the four departments that include both primary and secondary users. The memo said in part, “Only people who feel as if they require training need to make reservations for offsite training; all others should learn the system as they work with it on the job.” Only 3 of a possible 42 users signed up. The analysts were satisfied that the memo effectively screened people who needed training from those who did not.
a. In a paragraph, explain how the systems analysts got off the track in their approach to training. b. Outline the steps you would take to ensure that the right people at Cramtrack are trained. c. Suggest in a paragraph how the Web might be used to assist in training for Cramtrack.
