Question

AM spectrum consists of ________​

Answer 1

Answer:  Carrier frequency ,

Upper side band frequency ,

Lower side band frequency .

Step-by-step explanation:

The amplitude modulated signal consists of a carrier frequency component along with two sidebands around the main carrier. The frequencies obtained in the spectrum after the amplitude modulation are fc+fm and fc+fm where fc is the carrier frequency and fm is the modulating signal frequency.

Answer 2

AM spectrum consists of Carrier frequency with both Upper sideband frequency and Lower sideband frequency.

• Amplitude modulation (AM) is a modulation technique used for transmitting messages with a radio wave. It consists of three components:-

1. Unmodulated carrier frequency
2. USB
3. LSB

• If the carrier frequency is Fc, then the two sidebands produced by it are (Fc+Fm) and (Fc-Fm), where Fm is the frequency of the message signal.
