Goals:

To have a fundamental understanding of both analog and digital electronics; to be able to apply this understanding to debugging, specifying and integrating information technology systems; to be able to effectively communicate with other digital electronics professionals.

Prerequisites by topic: Mathematics, through trigonometry.

Outcomes:

1. Define resistance, inductance and capacitance.
2. Define and apply Ohm’s law in resistive circuits
3. Perform simple circuit analysis using KVL and KCL
4. Apply complex number mathematics to analysis of sinusoidal steady-state circuits
5. Calculate the complex impedance of inductors and capacitors at a given frequency.
6. Apply Ohms law, KVL and KCL to steady-state circuits containing inductors and capacitors as well as resistors.
7. Calculate the transient response of inductors and capacitors (charge and discharge rates)
8. Use circuit simulation software for circuit analysis.
9. Demonstrate understanding of any signal’s ability to be decomposed into a sum of sinusoids of various frequencies
10. Using capacitors, inductors and resistors, assemble and analyze high-pass and low-pass filters
11. On a semi-log graph, sketch the frequency response of a simple passive circuit
12. Describe the role of transformers in power supplies.
13. Perform conversions between the decimal, binary and hexadecimal number systems.
14. Demonstrate proficiency with signed and unsigned binary numbers
15. Perform 2’s complement arithmetic with binary numbers.
16. Demonstrate the use of combinational logic gates to implement logic functions
17. Use Boolean minimization techniques such as Karnaugh maps to reduce hardware requirements.
18. Use sequential logic components to retain system state in a circuit
19. Describe the construction and function of binary counters, registers, multiplexers, adders and decoders. Use them.
20. Report on individual reading in technical journals.

Laboratory projects: Labs are designed to reinforce the basic concepts being presented in the lectures. The labs held in a defined 3-hour time block each week. The labs tend to be exploratory in nature, although later labs have some simple design requirements.
