What is the second harmonic of an SSB frequency of 4146 kHz?

To determine the second harmonic of a single sideband (SSB) frequency, you multiply the fundamental frequency by two. The given SSB frequency is 4146 kHz. When you perform the calculation for the second harmonic, you take 4146 kHz and multiply it by 2:

4146 kHz × 2 = 8292 kHz.

This calculation shows that the second harmonic of the original frequency results in a frequency of 8292 kHz. Understanding harmonics is important in radio frequency communications, as these frequencies can influence signal quality and transmission characteristics. The other choices do not accurately reflect this doubling process; hence, they do not represent the correct value for the second harmonic.
