– 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

– 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 virtual instrumentation mcq

– 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 – Shift registers (on the edge of a

– Data Acquisition refers to the process of sampling real-world physical signals and converting them into digital numeric values. 11. In LabVIEW, a “Shift Register” on a loop is used to: A) Shift bits in a binary number B) Pass data from one loop iteration to the next (e.g., store previous value) C) Register a shift in the user interface D) Change the loop’s iteration count A) Flowchart B) Dataflow diagram C) Block diagram

Would you like an answer key or further explanations on any of these questions?

– A DAQ board typically includes ADCs (Analog-to-Digital Converters) and DACs (Digital-to-Analog Converters), along with signal conditioning. 6. Which hardware communication bus/standard is specifically designed for modular, high-speed, low-latency virtual instrumentation, often used in PXI systems? A) RS-232 B) USB C) PCI Express / PXI Express D) Bluetooth

– GPIB (General Purpose Interface Bus) is used to connect and control multiple traditional programmable instruments from a single PC controller. 9. Which of the following is a major advantage of virtual instrumentation over traditional instrumentation? A) Lower initial cost for every application B) Fixed and unchangeable functionality C) User-defined signal processing, analysis, and reporting D) Requires proprietary hardware for each measurement
