How many sidebands are present in a standard A.M. signal?
Official USCG Answer & Rule Citation
Correct Answer: Option C — Two
Standard Amplitude Modulation (A3E) produces two sidebands: the upper sideband (USB) and the lower sideband (LSB). These sidebands are located above and below the carrier frequency, respectively, and contain the sum and difference frequencies generated by the interaction between the carrier and the modulating information signal.
