Question

Match List-I with List-II (Communication Systems vs Bandwidth).

• A. A-I, B-II, C-III, D-IV
• B. A-I, B-III, C-IV, D-II
• C. A-IV, B-III, C-I, D-II
• D. A-IV, B-III, C-II, D-I

Hint:

AM → kHz, Telephone → kHz, FM/TV → MHz range.

Answer 1

The Correct Option is D

Concept: Different communication systems operate in different frequency ranges:
• AM broadcast → kHz range
• Telephone → few kHz
• FM → MHz range
• TV → MHz range

Step 1: Match AM AM broadcast typically operates around MHz (approx 1 MHz) \[ A \rightarrow IV \]

Step 2: Telephone Telephone bandwidth is about few kHz \[ B \rightarrow III \]

Step 3: Wideband FM FM operates in MHz \[ C \rightarrow II \]

Step 4: TV TV signals operate around higher MHz \[ D \rightarrow I \] \[ \therefore \text{Correct answer is (D)} \]
