Virtual Instrumentation Mcq -

– Real-world sensors often produce weak, noisy, or non-linear signals. Signal conditioning (amplifiers, filters, excitation) makes them suitable for the DAQ board. 14. Which of the following is NOT a typical component of a virtual instrumentation system? A) Computer with VI software B) DAQ hardware C) Physical front-panel hard keys (like a dedicated oscilloscope knob) D) Sensors/transducers

– VI’s key advantage is flexibility. The user can implement custom algorithms, data logging, automated test sequences, and remote monitoring – things fixed traditional instruments cannot do easily. 10. What does “DAQ” stand for in virtual instrumentation? A) Digital Analog Quantization B) Data Acquisition C) Direct Access Query D) Device Automatic Qualification

– PXI (PCI eXtensions for Instrumentation) is a rugged PC-based platform for measurement and automation, using PCIe for high throughput and specialized timing and synchronization. 7. What is the function of the “While Loop” structure in LabVIEW’s block diagram? A) Executes code a fixed number of times B) Executes code once and stops C) Continuously executes the code inside until a conditional terminal (e.g., stop button) becomes True D) Only runs if a specific error occurs virtual instrumentation mcq

– Shift registers (on the edge of a loop) remember values from previous iterations, which is essential for averaging, integrating, or detecting signal changes. 12. Which type of diagram is used to represent the flow of data in graphical programming languages like LabVIEW? A) Flowchart B) Dataflow diagram C) Block diagram D) Circuit diagram

1. What is the core philosophy of Virtual Instrumentation (VI)? A) To replace all hardware with software B) To use a general-purpose computer and software to create user-defined measurement and control systems C) To eliminate the need for analog-to-digital converters D) To exclusively use GPIB for instrument control – Real-world sensors often produce weak, noisy, or

– A While Loop repeats its subdiagram indefinitely until the stop condition is met. It is essential for continuous data acquisition or monitoring. 8. In virtual instrumentation, what does “GPIB” (IEEE-488) primarily provide? A) Power supply to instruments B) A parallel communication bus for controlling external bench-top instruments (like oscilloscopes, DMMs) from a computer C) Wireless connectivity for sensors D) Analog signal routing

Would you like an answer key or further explanations on any of these questions? Which of the following is NOT a typical

– VI leverages software (e.g., LabVIEW) and modular hardware to let users define their own instruments, rather than being limited by fixed-function traditional devices. 2. Which of the following best describes the fundamental difference between a traditional instrument and a virtual instrument? A) Traditional instruments are faster B) Virtual instruments have a fixed user interface (buttons/knobs), while traditional instruments are software-defined C) Traditional instruments have hardware-defined functionality, while virtual instruments are software-defined with the hardware providing acquisition/control D) Virtual instruments cannot measure real-world signals
