53、 Solution</p><p>　　With LabVIEW, you build graphical programs called virtual instruments (VIs) instead of writing text-based programs. You quickly create front panel user interfaces that give you the interac

54、tive control of your system. To add functionality to the user interface, you intuitively assemble block diagrams- a natural design notation for engineers and scientists.</p><p>　　Create the Front Panel</p

55、><p>　　On the front panel of your VI, you place the controls and data displays for your system by selecting ob jects from the Controls palette, such as numeric displays, meters, gauges, thermometers, LEDs, char

57、al Block Diagram</p><p>　　To program the VI, you construct the block diagram without worrying about the syntactical details of text-based programming languages. You do this by selecting objects (icons) from

58、the Functions palette and connecting them together with wires to transfer data among block diagram objects. These objects include simple arithmetic functions, advanced acquisition and analysis routines, network and file

59、I/O operations, and more.</p><p>　　Dataflow Programming </p><p>　　LabVIEW uses a patented dataflow programming model that frees you from the linear architecture of text-based programming languag

60、es. Because the execution order in LabVIEW is determined by the flow of data between nodes,and not by sequential lines of text,you can create block diagrams that execute multiple operations in parallel. Consequently, Lab

61、VIEW is a multitasking system capable of running multiple execution threads and multiple VIs in parallel.</p><p>　　Modularity and Hierarchy</p><p>　　LabVIEW VIs are modular in design, so any VI

62、can run by itself or as part of another VI. You can even create icons for your own VIs, so you can design a hierarchy of VIs that serve as application building blocks. You can modify, interchange, and combine them with o

66、include curve fitting, signal generation, peak detection, and probability and statistics. Measurement analysis functions can determine signal characteristics such as DC/RMS levels, total harmonic distortion (THD),impulse
