Abstract:
The presence of a data acquisition device in a modern physics laboratory lays the foundation for an advanced scientific investigation, due to the fact that the students can study the physical phenomena both qualitatively and quantitatively in a very complex manner. A physics experiment includes the acquisition, processing, storing and interpretation of the experimental data collected by the sensors associated with the studied physical quantities (temperature, pressure, force etc.). The analog signals transferred to a data acquisition device through the sensors are transformed into digital signals. These are later on processed with the help of a software application in order to monitor the variation of the physical quantities associated with the studied phenomena. In the present work we will focus, among other aspects, on the study of the phenomenon of electromagnetic induction, the acoustic spectral analysis (from a microphone), the measuring of the temperature (with a thermistor), the study of semiconductor devices (diodes, transistors), the resonance phenomenon in the electrical circuits RLC, using the data acquisition device NiDAQ 6008 and the graphical programming environment LabView.
