ELT 244 Electronic Circuit Analysis

Lecture Hours: 3
Lab Hours: 3
Credits: 4

Covers basic electronic devices and circuit designs. Emphasizes verifying and analyzing the designs, using the “R” parameters. Includes small-signal amplifiers, bi-polar circuits, FET circuits, oscillators, and power amplifiers. Includes some circuits analyzed using simulation software, while other circuits are constructed and analyzed, using laboratory test equipment. Promotes and supports sustainable and green technologies.

Prerequisite: ELT 141 and ELT 133, each with a grade of C or better; or consent of instructor.
Student Learning Outcomes:

Determine the DC and AC parameters of transistor amplifiers, both single and multi-stage circuitry.
