Course Information


Construction, analysis, and characterization of circuits with student-owned Lab-in-a-Box system. Experiments include: characterization of breadboard backplane wiring; component tolerances; Ohm's law; Kirchhoff's laws; series and parallel resistors; voltage and current dividers; delta-wye configurations; mesh-current and node-voltage analysis; superposition and Thevenin equivalents; inverting and non-inverting amplifier circuits; series RC and RL circuits; discharging LEDs and integrator and differentiator circuits. Introductory design experiments to include a simple voltmeter and a flashing traffic arrow.

Why take this course?

Circuit analysis and design using discrete R, L, and C components, as well as op-amps and transformers, is a fundamental skill for electrical engineers. Using a student-owned analog and digital trainer, a digital multimeter, and a software oscilloscope (equipment also used in four other required courses in the EE and CpE curriculum), the student learns to build and analyze real dc circuits and compare experimental results with theoretical results and computational models. This course complements the lecture course (ECE 2004) and stresses modeling, design, construction, measurement, and characterization skills for dc circuits.

Learning Objectives

  • Build circuits described in the catalog description and syllabus on a student-owned analog and digital trainer kit using student-owned tools and components to departmental wiring standards.
  • Measure and characterize the circuits built and described in MMLO (1) using a student-owned digital multimeter and software oscilloscope.
  • Analyze and model circuit performance using modern mathematical tools such as MatLab and PSpice and compare with measurements made in MMLO (2).
