The Fourier series discussed above allows us to decompose a signal to its constituent sinusoidal components at different frequencies.
This enables us to determine how the signal power is distributed in the frequency domain.
The Fourier series is used to analyze periodic waveforms.
What is Fourier series applicable for?
What is the Fourier series used for? Fourier series is used to describe a periodic signal in terms of cosine and sine waves.
In other other words, it allows us to model any arbitrary periodic signal with a combination of sines and cosines.
