Show Hint
Interlacing improves picture quality without increasing bandwidth.
Updated On: Jul 2, 2026
- make interlacing easier
- improve the picture resolution
- reduce peak power requirement
- reduce the required bandwidth
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Interlaced scanning divides frame into two fields.
Step 1: Even and odd lines Odd lines scanned first, then even lines.
Step 2: Need for odd number Ensures proper alignment of fields.
Step 3: Avoid overlapping Prevents same lines from repeating.
Step 4: Smooth motion Improves picture continuity.
Step 5: Conclusion \[ \boxed{\text{Make interlacing easier}} \]
Final Answer: \[ \boxed{(A)} \]
