Question:
In amplitude modulation of audio frequency \(700\) Hz, the appropriate carrier frequency to be used is
In amplitude modulation of audio frequency \(700\) Hz, the appropriate carrier frequency to be used is
Show Hint
In AM, the carrier frequency must be much larger than the modulating frequency.

- \(5\) MHz
- \(50\) MHz
- \(1000\) kHz
- \(350\) kHz
- \(1000\) MHz
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
For amplitude modulation, carrier frequency must be much greater than the signal frequency.
Given signal frequency:
\[
700\text{ Hz}
\]
Among the options, \(5\) MHz is sufficiently high and appropriate.
Hence,
\[
\boxed{(A)\ 5\text{ MHz}}
\]
