Goals: The objective of this course is to familiarize the engineering students with the fundamentals of electric circuit theory and instrumentation through experimentation. Formal laboratory reports are required to develop written communication skills. Safety in the laboratory is covered as appropriate.

Prerequisites by Topic:

• 1. Basic Electric Circuits or equivalent (ENGR 360)
• 2. Differential Equations or equivalent (MATH 353)
• 3. Electrical Physics or equivalent (PHYS 212)
• 4. Use of matrices and determinants in the solution of simultaneous algebraic equations (Cramer's Rule)
• 5. Use of the University computer in CMS time sharing mode and ability to compose FORTRAN arithmetic programs and "calling" programs.

Topics: the following laboratory experiments are performed:

• 1. Introduction to electric circuit experimentation: definition, units, devices, safety procedures, laboratory notebook requirements, and schedule (1 class)
• 2. DC measurements; fabrication of DC voltmeter (1 class)
• 3. Network analysis and measurement techniques; loop, nodal, superposition, Thevenin, Norton, and computer analysis (1 class)
• 4. Measurement of resistance of elements (1 class)
• 5. Characteristics of nonlinear circuit elements and analysis of circuits containing such elements (1 class)
• 6. Theory of operation of the oscilloscope; basic measurements using oscilloscope (2 classes)
• 7. AC measurements; fabrication of AC voltmeter; phasor analysis of RLC circuits (1 class)
• 8. Frequency response of resonant circuits (2 classes)
• 9. Magnetically-coupled circuits (transformers); measurement of mutual and self-inductance; determination of polarity and turns ratio (1 class)
• 10. Two-port networks; network parameters and equivalent circuits (1 class)
• 11. Transients in RL, RC, and RLC Circuits (1 class)

Major items of equipment used:

• 1. Tektronix Model 2225 Oscilloscope
• 2. Tektronix Model CFG250 Function Generator
• 3. Hewlett Packard Model 200 Signal Generator
• 4. Simpson Model 260 Multimeter
• 5. Fluke Model 37 Digital Multimeter
• 6. Hewlett Packard Power Supplies, Model 721A and 6212B
• 7. General Radio Model 1650A Impedance Bridge
• 8. Tektronix Model CFG250 Counter

Computer Usage:

• 1. One experiment assignment related to resistive circuits, using stored subroutines and programs with time sharing (CMS) system on IBM 3084 QXC VM/CMS.
• 2. Each student must write and execute program calling circuit analysis and plotting subroutines to generate input and output.
