This laboratory manual has been written to accompany the Third Edition of Electronics Technology Fundamentals by Robert T. Paynter and B.J. Toby Boydell. As such, the exercises have been arranged (as closely as possible) to follow the progression of topic coverage in the text. Exercises 1 through 12 deal with dc circuits and principles, and Exercises 13 through 27 deal with ac circuits and principles. Exercises 28 through 48 deal with discrete devices and circuits, op-amps, and op-amp circuits.
