#### Convergence of the Fourier Series

**Existence of the Fourier Coefficients**

is bounded if the signal is absolutely integrable over a single period

However, e

**xistence of the Fourier coefficients does not necessarily mean the Fourier series representation is identical to the original periodic signal.**
