How do you calculate sideband frequency?
The so-called upper sidebands are those lying above the carrier. Their frequencies are: C+M C+2M C+3M C+4M C+5M .... For example, if C:M is 1:2, that is, the modulator is twice the frequency of the carrier, then the first upper sideband is: C+M = 1+2 = 3.
What is a sideband frequency?
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.
How do you calculate sideband power?
The modulation index is m = 0.8. We will now substitute m=0.8, Pc = 124 W to find P. Therefore, the power in one of the sidebands in SSB SC modulation is 79.36 W.
How many sidebands are in FM wave?
Figure 7.9. Frequency modulation. Like AM, FM also produces sidebands. But unlike AM, which produces a single pair of sidebands for each frequency in the modulating signal, the FM process produces an infinite number of pairs of sidebands for each frequency in the information signal.
