Electronics Experiments

Physics 3340/4430/5430 Spring Semester, 2007

     All of the electronics experiments are designed to be completed in one week. All of the electronics experiments are designed to be completed in one week. The first two experiments are introductory. Experiments 3-5 cover operational amplifiers and would usually be done in sequence. Experiment 8 should be done after 3 and 4. Experiments 9 and 10 cover digital electronics, and should be done in sequence.
