Question

Medical instruments assist medical personnel in diagnosis and treatment. Arrange the correct sequence of an Instrumentation system.
A. Energy source
B. Signal processing
C. Display system
D. Measurement
E. Transducer/Sensor
Choose the correct answer from the options given below:

• A. A, E, D, B, C
• B. A, D, E, B, C
• C. E, B, A, D, C
• D. E, C, A, B, D

Hint:

Instrumentation = Energy source → Sensor → Measurement → Processing → Display.

Answer 1

The Correct Option is A

Step 1: Recall components of instrumentation.
An instrumentation system converts a physical quantity into a readable signal. Steps include: energy → sensing → measurement → signal processing → display.
Step 2: Arrange sequence.
- (A) Energy source: Provides required excitation.
- (E) Transducer/Sensor: Converts physical parameter into electrical signal.
- (D) Measurement: The raw data is measured and recorded.
- (B) Signal processing: Data amplified, filtered, digitized.
- (C) Display system: Final results shown to operator.
Step 3: Verify.
Sequence is A → E → D → B → C.
Step 4: Conclusion.
Correct order is option (A).
