What is harmonic analysis in Fourier series?
The analysis of harmonics is the process of calculating the magnitudes and phases of the fundamental and high order harmonics of the periodic waveforms. The resulting series is known as Fourier series. It establishes a relation between a function in the domain of time and a function in the domain of frequency.
What is harmonic analysis of time series?
Harmonic analysis of time series is an important technique in remote sensing to reveal seasonal land surface dynamics. However, frequency selection in the harmonic analysis is often difficult because high-frequency components are useful for delineating seasonal dynamics but sensitive to noise and gaps in time series.
How do you find the number of harmonics in a Fourier series?
They can be calculated by an=2T∫T0x(t)cos(2πntT)dtbn=2T∫T0x(t)sin(2πntT)dt.
