Fourier analysis is based on the idea that any time series can be decomposed into a sum of integral of harmonic waves of different frequencies. Hence, theoretically, we can employ a number of harmonic waves to generate any signal.
We will learn the basics of Fourier analysis and implement it to remove noise from the synthetic and real signals
