Why do sidebands occur in FM?
When the signal is modulated onto the carrier in the electromagnetic spectrum, that signal occupies the small portion of the spectrum surrounding the carrier frequency. It also cause sidebands to be generated at frequencies above and below the carrier frequency.
What is the importance of sidebands in AM?
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process. The sidebands carry the information transmitted by the radio signal. The sidebands comprise all the spectral components of the modulated signal except the carrier.
Is sideband AM or FM?
What is SSB? Single sideband is a special form of amplitude modulation (AM). What's so 'special' about it? Besides just encoding voice information with variations in signal amplitude, or power, SSB consumes a little less than half the bandwidth of a full “double band” AM signal.
How sidebands are produced in amplitude modulation?
Sides bands are produced during amplitude modulation. A modulating signal of frequency ωm is superposition on the carrier wave of frequency ωC. The resultant is passed through a square law device and band pass filter which generates side bands from ωC−ωm to ωC+ωm. This modulated wave carries the information.
