So here is where the Fractal-Function comes in, if it can be of help and service. However, while simulations with the aKS equation result in disordered ripple structures, they fail to reproduce the anisotropic sawtooth structures observed experimentally in the nonlinear regime [19{21]. However, the higher harmonics roll off much faster than in a square wave (proportional to the inverse square of the harmonic number as opposed to just the inverse). The RMS value of the waveform from t2 to T, is the same as the one from 0 to t2, with the difference that we need to replace t2. 2 is the following lemma: Lemma 1. In your lab notebook, be sure to derive the equations for computing the frequency input for each signal type.
