- Question
A given signal's second harmonic is twice the given signal's __________ frequency...?
Options- A. Fourier
- B. Foundation
- C. Fundamental
- D. Field
- Correct Answer
- Fundamental
ExplanationA given signal's second harmonic is twice the given signal's fundamental frequency. Harmonics are generated when there are non-linearities in an amplifier (there are always non-linearities). The worse the non-linearities, the more harmonics. A signal at 27.5 MHz (approximate frequency for US citizen's band) would have a second harmonic at 55.0 MHz (on US channel 2!). Can you see why there might be problems? A CB operator might do well to place a low-pass filter on his radio. - 1. What is an FET?
