Question

For amplitude modulated wave, carrier frequency should be message frequency.

• A. greater than
• B. equal to
• C. lesser than

Answer 1

The correct option is A greater than

There is a need for translating the original low frequency baseband message or information signal into high frequency wave before transmission such that the translated signal continues to possess the information contained in the original signal. In doing so, we take the help of a high frequency signal, known as the carrier wave, and a process known as modulation which attaches information to it.
