A signal's highest-frequency component is 2 kHz. According to the Nyquist sampling theorem, the minimum sampling rate needed to represent the signal without aliasing must be:
Correct answer: D - Greater than 4 kHz
In the standard NI-DAQmx programming model, which sequence shows the correct order of operations for a finite acquisition?
Correct answer: C - Create Channel → Timing → Start → Read → Clear
In LabVIEW's dataflow programming model, what determines the order in which two independent nodes (with no wires connecting them) execute?
Correct answer: A - Data availability at the node's inputs
Which of the following correctly lists the three elements contained in the standard LabVIEW error cluster?
Correct answer: D - status (Boolean), code (I32), source (String)
A Stop button is configured with the 'Latch When Released' mechanical action. During a run the user clicks it, the While Loop reads TRUE, and the loop stops. The VI is then run again and the user does not click the button. What value does the button's terminal return the first time it is read in the new run?
Correct answer: D - FALSE
A For Loop has its count terminal (N) wired to a constant of 10. A 6-element array is also wired into the loop through an auto-indexed input tunnel. How many times will the For Loop execute?
Correct answer: B - 6
A For Loop has its count terminal (N) wired to 4. A shift register on the loop is left uninitialized (nothing is wired to its left terminal). Each iteration adds 1 to the value from the shift register and passes the result back. An indicator wired to the shift register's output shows the final value. If the VI is run three times in succession without being closed, what does the indicator show after the third run?
Correct answer: C - 12
A floating-point (DBL) control containing the value 2.5 is wired to the selector terminal of a Case Structure that has cases labeled '2', '3', and 'Default'. Which case executes?
Correct answer: A - Case '2'
A For Loop must produce an output array that contains only the input elements greater than zero, excluding all others. Which output tunnel type accomplishes this?
Correct answer: C - Conditional output tunnel
A developer selects a portion of block diagram code and chooses Edit » Create SubVI. Which of the following does LabVIEW NOT do automatically?
Correct answer: B - Create a meaningful icon for the SubVI
