Subject Title
Digital Systems

Subject Description
This course familiarises the student with the basic principles of digital logic and digital integrated circuits, including Programmable Logic devices (PLDs). Upon completion of the course the student will be able to describe and analyse logic circuit operation and use a programmable logic development system to program a PLD to implement simple digital systems. The course examines the basis of digital logic in the binary number system and Boolean algebra, the operation of combinational and sequential logic and the general interfacing requirements of digital logic circuits. A number of applications, implemented with a PLD, will be examined including basic gate circuits, flip-flops, decoders and sequential circuits such as counters.

The student will be expected to use the World-Wide-Web (WWW) for reference material and documentation relevant to the course and to have email.

Credit Status
One subject credit in the Computer Engineering Technology program and the Electronic Engineering Technology program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  1. Understand and identify differences between analogue and digital electronics.
  2. Simplify logic circuits using the rules of Boolean algebra on circuit's derived expressions and/or truth table and vice-versa
  3. Apply appropriate digital circuit principles to convert a number to and from decimal, binary, hexadecimal number systems.
  4. Use digital circuit principles to determine and assess the main features of a digital waveform such as frequency, period and duty cycle.
  5. Interpret and derive truth table, Boolean expression and the logic circuit associated with DeMorgan expression and vice-versa circuit diagrams.
  6. Apply knowledge of basic functions of digital gates to design logic circuits.
  7. Modify Boolean expressions to their simplest forms using Karnaugh mapping techniques
  8. Design and implement priority Encoder, Multiplexer, De-multiplexer using logic gates and VHDL.
  9. Create simple combinational logic circuits in VHDL to verify the operation of combinational circuits.
  10. Prepare and design logic circuits from a word description of the requirement
  11. Troubleshoot, diagnose and resolve errors in VHDL code using appropriate procedures.
  12. Apply digital circuit principles to derive timing diagrams describing the pulsed operation of logic circuits.
  13. Document and summarize results and procedures.

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: http://www.senecacollege.ca/about/policies/academic-integrity-policy.html Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website http://open2.senecac.on.ca/sites/academic-integrity/for-students to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.

All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated. Information and assistance are available from the Student Conduct Office at student.conduct@senecacollege.ca.

Accommodation for Students with Disabilities
The College will provide reasonable accommodation to students with disabilities in order to promote academic success.
