Are harmonics related to fundamental frequency?
The harmonics are multiples of the fundamental frequency. So if the fundamental frequency is 100 Hz, the higher harmonics will be 200 Hz, 300 Hz, 400 Hz, 500 Hz, and so on. If the fundamental frequency were 220 Hz, the harmonics would be 440 Hz, 660 Hz, 880 Hz, and so on.
What is harmonic product spectrum?
HPS (Noll 1969) measures the maximum coincidence for harmonics for each spectral frame according to. (1) where R is the number of harmonics being considered. The resulting periodic correlation array is then searched for a maximum value of a range of possible fundamental frequencies.
How do you find the fundamental frequency of a Fourier transform?
In other words, the signal repeats every T seconds. The Fourier transform analyses the frequency content of a signal by decomposing it into sinusoids at different frequencies. A signal with a period T repeats at a rate of f0 = 1/T, which is referred to as the fundamental frequency of the signal.
