12. What is LabVIEW Simulation Platform ?.....cont’d
LabVIEW uses a graphic interface that enables different elements to
be joined together to provide the required flow.
Furthermore, LabVIEW isa systems engineering software for
applications that require test, measurement, and control with rapid
access to hardware and data insights.
LabVIEW offers a graphical programming approach that helps you
visualize every aspect of your application, including hardware
configuration, measurement data, and debugging.
This visualization makes it simple to integrate measurement
hardware from any vendor, represent complex logic on the diagram,
develop data analysis algorithms, and design custom engineering
user interfaces.
And remotely controlling certain process, mission and task….

From the proposed chart, the following statements can be stated:
- 78% of students are better understood the course topics
- 86% of students are strongly would attend such courses
As a result :
This course presents unique case that can be proposed for another courses in
the university, having in mind that PPU is the first university in Palestine
introduces LabVIEW platform in teaching such courses.
