The evolution of a course in computer-based data acquisition and analysis is described. The physics of the sensors, the physics of the system under study, and practical electrical measurement techniques are emphasized in this course, as well as computer hardware and software. Three experiments of particular physical interest are described in detail: heat flow in a metal plate, light-emitting diode characteristics, and the sounds generated by a speech chip.

Topics
Speech communication, Electrical properties and parameters, Electric measurements, Computer hardware, Data acquisition, Thin film deposition
