ECE 3274 Electronic Circuits Laboratory II (1C)

Design of amplifiers and other electronic systems to satisfy specifications. Bipolar and field-effect transistors, diodes integrated circuits and passive components are part of the hardware needed. Gain, bandwidth, feedback, stability are some of the design concepts needed.

What is the reason for this course?

This is the fourth laboratory experience for all EE students in which they learn to design and build more complicated circuits (systems) based on the theoretical and analytical concepts developed in 3204 and the lab skills learned in the 2074, 2274, and 3074 laboratory sequence. Unlike the earlier courses where the emphasis is on developing construction and analysis skills, this course emphasizes circuit design skills that require the student to create circuits that meet customer/user specifications.

Required for all EE and CPE majors. Typically offered: Fall, Spring. Program Area: Electronics.

Prerequisites: 2274 and 3074. Corequisite: 3204.

Why are these prerequisites or corequisites required?

The student must have completed the previous laboratory sequences that include 2274 and 3074 as these courses develop the necessary lab skills that involve instruments such as function generators and oscilloscopes. The laboratory design projects for this course are based on circuit theory taught in 3204 and are closely aligned with the lecture material. Thus, 3204 must be taken at the same time as 3274.
