Examples of oscillation waveforms that are constructed for use in FF, Sym, and FR experiments with a frequency f = 1 Hz. As indicated by the shape of the FF waveform, there is a portion of the cycle with rapid velocity followed by a slow reverse motion. The opposite behavior is illustrated in the FR waveform example, whereas the Sym waveform is simply a sinusoid.
