Internally, however, modern computers deal only with discrete quantities specifically, they deal only with quantities take on only two values: on or off. But even measurements of discrete phenomena tend to be confounded by noise and produce continuous data. There are, of course, intrinsically discrete exceptions to this rule, like the quantization of charge or the quantum hall effect. Our world is largely analog and continuous quantities vary smoothly. Assuming that the DAQ digital output high level is exactly 5V, what is the full scale value (largest output) of the DAC in this exercise? Given the DAC in Exercise 10.2 has a resolution of 5 bits, how close to their ideal values must each resistor be?Ģ.
Plan out how to perform Lab exercises in this write-up.Īll parts spec sheets are located on the Physics 111 Library site.ġ.Begin and if possible complete programming tasks in this lab write-up.Perform any circuit calculations use MatLab or anything that can be done outside of lab RStudio (freeware).Answer the pre-lab questions utilizing the references and this write-up.Two versions of the programs are typically available for download: an executable version that should run without LabVIEW (but requires a large download from National Instruments, which should occur automatically, and only needs to be done once) and should run on PC’s, Mac’s and Linux boxes and the original LabVIEW source code which requires LabVIEW.īefore coming to class complete this list of tasks: Many of these programs can be downloaded from the 111lab\BSC Share\ on the U: Drive from the 111-Lab computers.
Several LabVIEW programs are mentioned in this lab writeup. In this lab you will learn how to convert data between analog and digital, and the many pitfalls in doing so.
