Fourier
Foundation
Fundamental
Field
Answer is Right!
Answer is Wrong!
The correct answer is C. Fundamental.
A harmonic is a frequency that is an integer multiple of the fundamental frequency. The fundamental frequency is the lowest frequency in a complex waveform. The second harmonic is twice the fundamental frequency, the third harmonic is three times the fundamental frequency, and so on.
In the case of a given signal, the second harmonic is twice the given signal’s fundamental frequency. This is because the second harmonic is a frequency that is an integer multiple of the fundamental frequency, and the fundamental frequency is the lowest frequency in the complex waveform.
The other options are incorrect.
- Option A, Fourier, is incorrect because it is not a frequency. The Fourier transform is a mathematical tool that can be used to decompose a complex waveform into its constituent frequencies.
- Option B, Foundation, is incorrect because it is not a frequency. The foundation of a building is the part that supports the weight of the building.
- Option D, Field, is incorrect because it is not a frequency. A field is a region of space in which a physical quantity, such as a force or a magnetic field, has a value at every point.
