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 are the sideband frequencies?
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.
What is upper sideband and lower sideband?
In an amplitude-modulated carrier, the frequency band that (a) is located above or below the carrier frequency and (b) results from the modulation process. Note: The sideband frequencies above the carrier frequency comprise the upper sideband and those below the carrier frequency comprise the lower sideband.
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.
