When this is the case the instructor must look for creative alternatives to help meet the desired objectives. This report examines how a virtual laboratory was created to model and analyze

The students were able to printout various waveforms (e.g., signals of different frequencies/network media) that are similar to output from test equipment that would have otherwise been cost prohibitive. The activity proved to be valuable in helping students to understand an otherwise difficult concept that is central to modern networking applications. Such simulation is not limited to network signals, but may be applicable in many situations where the artifact under study may be described mathematically.
