The Fourier series expansion for a rectangular pulse wave with period T and pulse time Ï is. Note that, for symmetry, the starting time (t = 0) in this expansion is halfway through the first pulse. The phase can be offset to match the accompanying graph by replacing t with t - Ï/2.he Fourier series expansion for a rectangular pulse wave with period T and pulse time Ï is.
