The transition between minimum to maximum is instantaneous for an ideal square wave; this is not realizable in physical systems. Square waves are symmetrical in nature, with every half of the cycle in a square shape. For functions of two variables that are periodic in both variables, the trigonometric basis in the Fourier series is replaced by the spherical harmonics.
