Course Description

Third course in digital electronics continues prior coverage of digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) with additional conversion topologies, a more detailed analysis of the Nyquist sampling theorem, additional coverage of programmable logic devices (PLDs), and the implementation of sequential state machines. Includes a 3-hour per week laboratory. Prerequisite: EET 122 Audit available.

Addendum to Course Description

In the laboratory, the student will construct several circuits including a discrete circuit that performs digital-to-analog conversion and a circuit that performs analog-to-digital-conversion. The student will use standard laboratory instrumentation to verify the operation of each circuit. The student will also use PC-based electronic circuit simulation software to simulate the operation of several circuits. The Nyquist sampling theorem will be studied in both the time and frequency domains. The use of a programmable logic device (PLD) and a PLD programming language will be explored for the implementation of state machines.

Intended Outcomes for the course

  1. To be able to describe the sequence of steps performed by various topologies used for analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC).
  2. To be able to apply the mathematical relationships in the Nyquist Sampling Theorem to determine the required sampling frequency, filter cutoff frequencies, ADC/DAC resolutions, data bandwidth, and guardband for a sampling system.
  3. To design and implement sequential state machines using state graphs.
  4. To describe the overall architecture of common programmable logic devices (PLDs) and how they are programmed.
  5. To construct digital circuits, use standard laboratory instrumentation to verify the operation of the circuits, and use PC-based electronic circuit simulation software

Outcome Assessment Strategies

Assessment methods are to be determined by the instructor. Typically, in-class quizzes, exams and weekly homework assignments will be used. Laboratory assessment will be by reports and/or practical skills testing
