amplitude
means average power of th component
Real and even property
- is real and even → is real and even
Determination of Fourier Coefficients
how to derive coefficients from synthesis equation form
We can consider when inside of
Convergence of the Fourier Series
Existence of the Fourier Coefficients
is bounded if the signal is absolutely integrable over a single period
However, existence of the Fourier coefficients does not necessarily mean the Fourier series representation is identical to the original periodic signal.
