Electronic devices and circuit's laboratory manual for junior level college electronic design course. The manual consist of ten experiments of multiple parts and six chapters of descriptions of the laboratory equipment such as dual display multimeter, triple output DC power, oscilloscope, and function generator. The manual also contains ten appendices of devices schematics and lab procedures. This laboratory manual is designed to accompany one semester course or quarter class in electronic devices and circuit. Each experiment in this manual should take one week to perform. Normally, students perform the experiments in groups of two. Ideally, a student more comfortable with the equipment used in this laboratory, and especially the general-purpose oscilloscope, will be appointed group leader. The function of the group leader is to supervise the activities of the group and become its spokesperson in its dealings with the laboratory instructor. In those instances where the group leader has an extensive technical background, he/she should let the less-experienced partner do most of the routine work, limiting his/her activities to checking and trouble-shooting circuits as well as answering questions that may arise during the course of the experiment. All parts of each experiment in this manual that students are to perform must be simulated with PSpice. The simulations check the validity of the experimental measurements through theoretical means. Normally, a larger-than-10% discrepancy between experimental and simulated results is an indication of either erroneous experimental techniques or erroneous entry of the experimental results into the computer. In either case, appropriate corrective actions are suggested. During the first week of Experiment 1, the various resistors, capacitors, diodes, transistors and other devices needed to perform all the experiments in this manual should be provided by the laboratory instructor. Additionally, students should include with their kits a number of short pieces of 22 AWG wire; these are to be used to wire their circuits in conjunction with their experimenter circuit board. Note that each student should possess his/her own circuit board which must be brought to the laboratory each time it meets.
