Fourier Series of any periodic function x(t) can be obtained if,
1. \(\mathop \smallint \limits_{t_1} ^{\infty }|x\left( t \right)|< \infty\)
2. Signal x(t) must have a finite number of maxima and minima in the expansion interval.
3. x(t) can have an infinite number of finite discontinuities in the expansion interval.
4. x2(t) is absolute summable
