Question

Frequency components of an AM wave (m = modulation index) are

• A. Carrier frequency ${\omega }_c$ with amplitude A
• B. Upper side band ${\omega }_c-{\omega }_m$ having amplitude A/2
• C. Lower side band ${\omega }_c+{\omega }_m$ having amplitude A/2
• D. All of the above

Answer 1

The correct option is A Carrier frequency ${\omega }_c$ with amplitude A

By definition the carrier frequency(${\omega }_c$) with Amplitude A is called the frequency component of an amplitude modulated wave.
