A.1 Fourier Series
) [Fourier Series] Let the signal x(t) be a periodic signal with period T0.If the following conditions are satisfied 1. x(t) is absolutely integrable over its period

1/21



T0

0

| x (t ) |dt < ∞

2. The number of maxim and minima of x(t) in each period is finite 3. The number of discontinuous of x(t) in each period is finite then x(t) can be expanded ……
