Purpose
1.To help further familiarize the student with the LabVIEW programming environment.
2.To demonstrate some of the important issues involved in digital-analog data conversion.
3.To illustrate the essential components in a virtual function generator.
4.To show the effect of noise and filtering on a signal.
5.To show the workings of the case structure.
Pre-Lab Exercises
Complete the following exercises before the lab period for Lab 2.
1.Consider the Figures 1 and 2, which could represent the oscillating movement of a piece ofmachinery with respect to time.Figure 1 has a clean, filtered sine wave while Figure 2shows an unfiltered wave.
For each figure, what are the amplitude, period, and frequency ofthe wave?Report the frequency in both Hertz (Hz) and in radians per second?
2.What is electrical noise and what are some possible sources for it?
