Square wave (frequency)


A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. The frequency equation of the square wave can be written as the Fourier series.(Represent an ideal square wave with an amplitude of 1)
