Course Description

Combines digital and analog circuit topologies. Explores Analog/Digital conversion and memory circuits. Includes modification, troubleshooting and analysis of circuits with a programmable logic device (PLD) using a hardware descriptive language (HDL), such as VHDL or Verilog. 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

Upon successful completion students should be able to:
1. Convert signals from analog to digital and digital to analog. 
2. Build and simulate electrical digital systems circuits and perform measurements with electronic test equipment. 
3. Write technical reports using collected experiment data. 

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
