DIANA - DIgital ANAlysis -Interactive Tutorial for Digital Logic Design and Digital Signal Processing

This tutorial system reviews some of the basic concepts from the first half of the ELEN/COEN 121 and allows the student to interactively change functions and view canonical forms, simplified forms, and Kmap minimizations. The Quine McClusky method for minimization is also demonstrated. For Digital Signal Processing topics in uniform average filters and windowed cosine filters are available. These FIR filters are covered in ELEN 133. Tutorial demonstration of aliasing can be found in the Linear Systems subject area.


No preparation is required. The tutorial is very easy to run and all instructions appear on the screen.




A large screen with five subject buttons will appear. The currently active subjects are Combinational Logic Design, Linear Systems, and Digital Signal Processing.

Select a subject area by clicking on the appropriate icon as indicated on the screen. After a subject area is selected a new screen will appear with a topic list for that subject. Select a topic and then select DEMONSTRATION or REVIEW and follow instructions on the screen. Instructions for ending a topic or subject are also on the screen. In the normal demonstration mode you will be able to change parameters and view the results. In the automatic demonstrattion mode you can step through a sequence of displays in which parameters have been selected, and a brief description of the display is shown in the lower right. In the SELF TEST mode you can select parameters as you did in the normal demonstration mode, but results are not shown until you request them.


This is an interactive on-line tutorial and is not intended to create printed or plotted output on paper.


Topic names preceded by ** are not fully converted to MOTIF, and are not currently active. It is expected that they will be activated in a future version. The most complete subject area is 121 Combinational Logic Design. All active topics have a Demonstration and Self Test. Some active topics may not have Review or Questions.

Note that after a topic is selected the large display window will remain blank until Review, Demonstration, Self Test, or Questions is selected.
