ECED2200 - Intro to Digital Circuits
Last updated
ECED2200 is a basic introduction to digital electronics course, which I taught as a summer course a few times at Dalhousie. This page holds the resulting lectures and labs I created for this course, which are used during some of the regular course as well.

WARNING: If you are a student at Dalhousie University, be aware not all material on this page may be relevant. e.g. the Course Syllabus, textbook, assignments, and exam info are ONLY valid when I'm the instructor. They will be WRONG if you are taking the regular course. As a reference I leave the previous years info here, in case you want to follow along. Most of the labs/slides should be relevant for all years however.
Textbook & Other Resources
The recommended text is "Bebop to the Boolean Boogie" by Clive Maxfield. This book is enjoyable to read (as far as digital logic books go) and will be an excellent reference. You can buy it from e.g.: Amazon.ca or Amazon.com, however at Dalhousie (and probably other universities) you have access to the electronic edition for free.
You may access it using the following link which should work when ON university Campus. If you aren't at a university yourself, you might be able to access this resource by using a computer in the library if they provide open access.
I have been told that the Kindle edition of this book has low-quality figures. You can try the Google Play version if you want an E-Book if your institution doesn't provide access.

Course Notes
A version of the course notes is available online, which is based on much older course material: ECED2200 Course Notes . Many of the examples follow the lecture slides, so you may find these notes useful. Note the ECED2200 Course Notes are copyright Dalhousie University, and are excluded from the CC License.

Labs
Where a 'hand-in-sheet' is present I don't expect a full lab report (i.e. labs 1,3,4,5).
For labs 2 and 6 you need to do a full lab report, as described in this document. Again if your instructor is using these files they have have different requirements.
| Lab No. | Lab Name | Instructions | Required Files | Videos + Slides |
| 1 | Basic Gates: Breadboard, Simulator, and Programmable | Procedure Hand-In Sheet | 1: BORA Eraser 2: Example project | Slides Video Part 1 Video Part 2 |

| 5 | Shift Registers & Serial Protocols | Procedure Hand-In Sheet | Example Project (Standard) | |
| 6 | Counters, Pulse Width Modulation | Procedure | Example Project (Standard) | |
