Which of the following is a primary reason for using automation architectures?
Reduce memory size
Eliminate programming
Improve control accuracy
Increase wiring complexity
A communication facility that sends signals over long distances with minimal loss is:
Optical fiber
RS-232 cable
USB cable
Parallel port
A system showing delayed actuator response but correct sensor readings may indicate:
Transmission delay in communication
Fault in sensor
Too much memory
No interfacing issue
To design an effective interfacing strategy for multiple sensors, engineers must:
Avoid using signal conditioning
Implement appropriate A/D conversion and noise filtering
Use only digital sensors
Ignore grounding
A digital twin of a wind turbine is primarily used to:
Store employee data
Predict turbine behavior
Control office lighting
Replace physical sensors
To improve logistic regression performance, the most effective step is:
Remove training labels
Apply feature scaling
Disable gradient descent
Increase noise
UAVs in industrial inspection reduce cost mainly by:
Increasing human involvement
Reducing the need for manual inspection
Replacing all machinery
Eliminating data analysis
To design a smart metering communication system for dense cities, engineers must:
Use narrowband IoT (NB-IoT)
Use only wired connections
Reject modem technology
Store data locally only
A BAN ECG sensor shows abnormal data but the patient is fine. The issue may be:
Faulty electrodes or motion artifacts
Perfect signal quality
Ideal sensor placement
Accurate filtering
When creating a pharma IIoT architecture, the BEST design is:
Sensors → Edge gateway → Cloud analytics → Automated alerts
Sensors but no connectivity
Data stored manually in books
Cloud without sensors
