Students must complete the laboratory assignments in order to obtain a passing grade for the course. Students will perform experiments in groups of 2 or 3 as assigned by the lab instructor. All partners are expected to take an active part in preparation for and execution of each experiment. Each student in a group is responsible for a separate and full report on each experiment. Lab partners will be rotated every week. Lab reports are not accepted if the student did not attend the associated lab.

Laboratory 1: Introduction to Labview O BJECTIVES To become familiar with the LabVIEW programming environment o understand front panels, block diagrams, icons and connector panes o create and save programs in LabVIEW To use LabVIEW to create virtual instruments for generating various waveforms and saving data for post-acquisition analysis. I NTRODUCTION LabVIEW ( Lab oratory V irtual I nstrument E ngineering W orkbench) is a graphical programming language that is used to create programs for data acquisition, data analysis, and control. For example, engineers use LabVIEW software to take measurements and process the data in real-time during laboratory testing. LabVIEW can also be used in real time control such as control of dynamic systems and robotics. Programs produced in LabVIEW are called Virtual Instruments (VIs); they are called virtual instruments...
