Prospectus

Physics 116C introduces techniques for making physical measurements using computer-based instrumentation. We use the LabVIEW programming system, which finds wide application in physics (and other) labs. The course will also cover experimental techniques, statistical analysis of data, the sampling theorem, finite Fourier transform techniques, noise spectra and other issues beyond the programming language itself in a series of lectures (see outline below). A brief overview of other approaches to data acquisition and experiment control will also be provided.

Physics experiments at the level of Physics 122 are a key component of the course. These will require complete reports.

The text by Essick is essentially a series of well-illustrated exercises and experiments for learning the LabVIEW language and applying it to mathematical problems as well as to data acquisition. This will be the focus of the first 6 weeks of the course (supplemented with related lectures and the Geiger counter and muon lifetime experiments). You should obtain the student edition of LabVIEW so you can work outside of the lab times to complete these assignments on your own computer (let me know if you have a problem here).You will need to upload your work on the assigned exercises in Essick to your SmartSite dropbox so they can be checked by the TA. This will be considered as part of your lab work. The initial labs will provide some time to work on the assigned Essick exercises.

Prerequisites: Physics 9D, 116B, Math 22AB or consent of department
