Question 3-11B3
Element 3 (GROL)What is the second harmonic of SSB frequency 4146 kHz?
Explanation
A harmonic is an integer multiple of a fundamental frequency. The "second harmonic" specifically refers to the fundamental frequency multiplied by two.
For an SSB frequency of 4146 kHz, its second harmonic is calculated as:
4146 kHz * 2 = 8292 kHz.
Therefore, 8292 kHz is the correct second harmonic.
Option B, 4.146 MHz, is simply the fundamental frequency expressed in megahertz (4146 kHz = 4.146 MHz), not a harmonic. Option C, 2073 kHz, is half the fundamental frequency (4146 / 2), which is a subharmonic. Option D, 12438 kHz, is three times the fundamental frequency (4146 * 3), making it the third harmonic.
