By Kehtarnavaz N

This e-book combines textual and graphical programming to shape a hybrid programming process, permitting a better technique of construction and interpreting DSP structures. The hybrid programming process permits using formerly built textual programming recommendations to be built-in into LabVIEW's hugely interactive and visible surroundings, supplying a better and faster process for construction DSP structures. This e-book is a perfect creation for engineers and scholars trying to enhance DSP structures in speedy time. beneficial properties . the one DSP laboratory ebook that mixes textual and graphical programming . 12 lab experiments that contain C/MATLAB code blocks into the LabVIEW graphical programming atmosphere through the MathScripting characteristic . Lab experiments masking easy DSP implementation themes together with sampling, electronic filtering, fixed-point info illustration, frequency area processing . fascinating functions utilizing the hybrid programming technique, equivalent to a software-defined radio approach, a 4-QAM Modem, and a cochlear implant simulator

Nasser Kehtarnavaz is Professor of electric Engineering at college of Texas at Dallas. He has written various papers and 5 different books referring to sign and snapshot processing, and often teaches electronic sign processing laboratory classes, for which this ebook is meant. between his many pro actions, he's Coeditor-in-Chief of magazine of Real-Time snapshot Processing, and Chair of the Dallas bankruptcy of the IEEE sign Processing Society. Dr. Kehtarnavaz is a Fellow of SPIE, a Senior Member of IEEE, and a pro Engineer.

Example text

Enter 10 so that the code inside it gets repeated 10 times. Note that the current loop iteration count, which is read from the iteration terminal, starts at index 0 and ends at index 9. Place a Random Number (0–1) function (Functions » Programming » Numeric » Random Number (0–1)) inside the For Loop and wire the output terminal of this function, number (0 to 1), to the border of the For Loop to create an output tunnel. The tunnel appears as a box with the array symbol [ ] inside it. For a For Loop, auto-indexing is enabled by default, whereas for a While Loop, it is disabled by default.

As the final step of configuring the FP, align and distribute the objects using the appropriate buttons on the FP toolbar. To set the outputs, locate and place a Numeric Indicator, a Round LED (Controls » Modern » Boolean » Round LED), and a Gauge (Controls » Modern » Numeric » Gauge). Edit the labels of the indicators as shown in Figure L1-12(a). Now let us build the BD as shown in Figure L-12(b). There are five control and indicator icons already appearing on the BD. Right-click on an open area of the BD to bring up the Functions palette and then choose Select a VI.

34 Getting Familiar with LabVIEW: Part I Placing probes on wires creates probe windows through which intermediate values can be observed. A probe window can be customized. For example, showing data of array data type via a graph makes debugging easier. To do this, right-click on the wire where an array is being passed and choose Custom Probe » Controls » Modern » Graph » Waveform Graph from the shortcut menu. As an example of using custom probes, a Waveform Chart is used here to track the scalar values at probe location 1, a waveform graph to monitor the array at probe location 2, and a regular probe window at probe location 3 to see the values of the Indexing Example VI.
