Fourier transform theory

Now, a step function (or a square wave form) can be represented as a sum of sine waves of frequency , where is the frequency of the square wave, and we recall that frequency = 1/wavelength. Normally, frequency refers to the rate of repetitions per unit time, that is, the number of cycles per second (Hertz).
