This tutorial and simulation material introduces the static and clock multiplexers through simulation. The text material covers the related circuit theory and the implementation methods of algebraic manipulation, Karnaugh map and the numerical method. There are exercises related to each section. It is a technical (mathematical) overview of how a multiplexer works.
Type of Material:
This material is a tutorial with simulation.
Recommended Uses:
This may be used as additional learning material in a Computer Science hardware course.
Technical Requirements:
Computer with browser and connection to the Internet. The simulations were written for a Netscape browser, but instructions are available for running the simulations on a PC, Unix or Mac platform.
Identify Major Learning Goals:
fter completing this module, the student will be able to identify two types of multiplexers and explain three methods of related circuit implementations.
Target Student Population:
The target population is a ollege/University first year Enginnering or Computer Science student. It would also be appropriate for graduate student in the same disciplines.
Prerequisite Knowledge or Skills:
Understanding of Boolean algebra expressions and functions as well as gates and functions.
Content Quality
Rating:
Strengths:
Each topic is logically constructed into sections of an introduction to the method, the algebraic presentation and an exercise section. Consistent icons identify each section. Each topic has either a simulation (types of multiplexers) or a figure supporting the information presented.
The site is well written, and has comprehensive illustrations.
Concerns:
There was a broken link to the exercises in the algebraic method topic. The link to the sequential switching tutorial circuit guide has not been developed. The quality of the multiplexer simulations has not been tested by this review. This is an extremely technical site that may not be appropriate for all.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
Should the student not be up-to-speed on the prerequisite knowledge, tutorials on those subjects are available as well. There are simulations supporting the visual learner, as well as related exercises and illustrations. There are frequent links to submit a comment or question. Response has not been tested. Good information is supplied.
Concerns:
The quality or user friendliness of the simulations could not be verified at the time of this review. A technical background is required.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
Run time engines are provided for platforms other than Netscape. They have to be installed. Each page has a table of contents that links into the material for fast access. All of the material for each topic is presented on one page. A glossary is available on the site map page. The site is well laid out, with good examples.
Concerns:
The material was developed in 1998. The recommended browser configurations to run simulations might be different with current browsers. There is no support mentioned for running the simulations on Monzilla-based or Opera browsers.
